  • Parameter query or cascading combo boxes

    In my Access 2013 web app, I have a form for entering a specific type of  activity.  I am using a related item control to add contacts to each activity.  The main table is Activity, the related Item Control is based on (join table) Assignment.
     So far so good.
    Now on the popup view I need to be able to assign contacts to the activity and I need to filter the choice of contacts based on location and group, so for example, when I open the contact combo box, I see only my volunteers from office 1, or only my staff
    from office 2, etc.  Is this best accomplished by cascading combo boxes? Or should I somehow use a parameter query? I have tried the cascading combo boxes but so far have not been able to get them to work. 
    FYI: In the contacts table, every contact has a location and group. Also, I have one table for location and one for group, so that I can use those in look ups. 
    My join table is: Activity ID (look up to activity table) / Contact (look up to Contact Table) 

    Hi,
    >>
    I need to filter the choice of contacts based on location and group
    Is this best accomplished by cascading combo boxes?
    I have tried the cascading combo boxes but so far have not been able to get them to work.
    <<
    In this case, I will suggest you using the Combo Box control which has the build-in support on cascading feature.
    And what do you mean by “not been able to get them work”? I did a quick test and it worked as expected.

  • I have NO scripting experience but am attempting to create "cascading combo box" with two boxes.

    I have copied and edited to the best of my ability several options but keep getting errors, mostly illegal character on line...
    I do not have LifeCycle, merely Adobe Acrobat IX (and a trial version of Acrobat XI PRO) and the extent of my knowledge ends at placing fields, text, etc. . .
    The scenario is as follows:
    On the document, there are two combo boxes
    1- "DeptName"
    2- "Position"
    The goal is to be able to select one of 15 different departments, and based on that selection, choose from between 2 to 15 different positions for that corresponding department.
    Below is what I was hopeful would work, but alas - FAIL!!
    If anyone could assist it would be GREATLY APPRECIATED!
    myDeptNameValues =
    "ADMINISTRATION – RSADMN (8171)",
    "BEVERAGE – RSBEV (8174)",

    The above code was placed in the document script.  Within the format area of the "DeptName" box, I have the following code placed in the keystroke script.
    if( event.willCommit )
    if(event.value == "")
    this.getField("box2").clearItems();
    else
    SetFieldValues(event.value);
    I have spent the past four days, more than 18 hours in the last two alone trying to nail this down and I can't explain how completely defeated I feel, not to mention frustrated.
    Again, thanks for your help!!

    I suppose I am not meant to figure this out.  I am trying my absolute hardest to accomplish compiling this document without having to resort to asking someone to do it for me as I have noticed in a few other threads, but it just seems to get more frustrating.  I have accomplished the first thing I set out to do and I completely appreciate your assistance with that.  My issue now is that i have other text fields I want to automatically fill based on the selection of the very same DeptName combo box.  I can make the cascading/dependent box work with the initial DeptName box, or all the additional text fields with the DeptName box, but cannot seem to accomplish having them work together.  I have been working daily, reading blogs/forums, watching videos all in an effort to complete this before it's needed on Feb. 2. 
    Is it possible to make 7 text fields and a combo box(B) fill based on the selection of a separate combo box (A), and then have 5 more text fields automatically fill based on the selection from the secondary box (B)?  I can make it all happen individually, meaning only the text fields for one box or the combo box (A to b) but not in conjunction.

    This is the file, if it helps to see what I'm hoping to accomplish

  • Cascading Combo Box

    I have a page with 2 cascading Single Once Choice (SOC). Price list SOC and Product list SOC. The requirement is that a customer ID will be sent into the page via url parameters which will filter the dropdown value for Price List. Price list SOC will drive what the Product list dropdown values are. The model design is as follows
    * Price List VO with a view criteria for customer ID
    * Product List VO with a view criteria for PriceList ID
    * A MainVO that uses both PriceList VO and Product List VO with 2 VA (Price List ID and Product List ID) and 2 LOVs PriceListVO1 and ProductListVO1
    We used the LOVs to create 2 SOCs in the page with partial trigger setting. We create an AM method to receive the value from the URL param and parse it to determine the customer id and set the PriceList view criteria. We are using a taskflow that actually receives the url values and calls the AM method to process it and set the PriceList VO and then pass the flow control to the page with SOCs.
    We were able to make the following work
    * Taskflow is able to receive the values from url and call the AM method
    * AM method executes the logic to determine customer ID and is able to set the Price List VO customer ID and execute Price List VO query. I used VO.getrow count to check the row count and notice that the VO is correctly set
    But when the Taskflow passes the control to the pages with cascading SOCs it is not working. The PriceList SOC does not have any values indicating that the VA PriceListVO1 which is based on PriceList VO does not have any rows indicating that the criteria is not set.
    I dont know what I am doing wrong. I tried to programmatically access the VA - PriceListVO1 in the same AM method and set the Viewcriteria to CustomerID execute the query but the result is the same. When the taskflow is passing the control to page the PriceList VO criteria are all removed.
    Kndly help

    HI,
    If you use pageFlowScope use that to pass parameter instead UPL passing.

  • How can I make the combo box turn to the value of black.

    When the show button is pressed (and not before), a filled black square should be
    displayed in the display area. The combo box (or drop down list) that enables the user to choose the colour of
    the displayed shape and the altering should take effect immediately.When the show button is pressed,
    the image should immediately revert to the black square, the combo box should show the value that
    correspond to the black.
    Now ,the problem is: after I pressed show button, the image is reverted to the black square,but I don't know
    how can I make the combo box turn to the value of black.
    Any help or hint?Thanks a lot!

    item = form.Items.Add("oMese", SAPbouiCOM.BoFormItemTypes.it_COMBO_BOX)
                    item.Left = 245
                    item.Top = 5
                    item.Width = 80
                    item.DisplayDesc = True
                    combo = item.Specific
                    combo.DataBind.SetBound(True, "", "uMese")
                    combo.ValidValues.Add(1, "Gennaio")
                    combo.ValidValues.Add(2, "Febbraio")
    event handling:
    inside ItemEvent in case the item is selected
    Case SAPbouiCOM.BoEventTypes.et_COMBO_SELECT
                        Select Case pVal.FormUID
                            Case "PRG_UFM_0002_RegIVAAcq"
                                retCode = oTy_RACQ.FormComboSelect(pVal, BubbleEvent)
      Public Shared Function FormComboSelect(ByVal pVal As SAPbouiCOM.ItemEvent, _
                                               ByRef BubbleEvent As Boolean, _
                                               ByRef funCaller As Object, _
                                               ByVal funCallerID As Integer, _
                                               ByRef aForm As SAPbouiCOM.Form) _
                                               As Integer
            Dim msg As String
            Dim edt As SAPbouiCOM.EditText
            Dim cmb As SAPbouiCOM.ComboBox
            Dim obt As SAPbouiCOM.OptionBtn
            Dim cbx As SAPbouiCOM.CheckBox
            Dim mtx As SAPbouiCOM.Matrix
            Try
                If pVal.Before_Action = True Then
                    Select Case pVal.ItemUID
                        Case "oMese"
                            Dim stre As New strEstremi
                            cmb = aForm.Items.Item("oMese").Specific
                            edt = aForm.Items.Item("anno").Specific
                            If Not cmb.Selected Is Nothing Then
                                GetEstremiPeriod(edt.Value, cmb.Selected.Value, "M", stre)
                                edt = aForm.Items.Item("dtFrom").Specific
                                edt.String = stre.dtFrom
                                edt = aForm.Items.Item("dtTo").Specific
                                edt.String = stre.dtTo
                            End If
    end function
    thank you I hope is enough otherwise please tell me

  • How do I retrieve data from combo boxes?

    The past weekend I spent my whole weekend trying to find this
    out and gone through the top 10 pages on google trying all sorts of
    things. I would be grateful for anyone who can help me.
    I have 6 combo boxes in a booking form and I need to retrieve
    the data when someone click submits which gets forwarded on to php
    then my mailbox. They are called box1_cb, box2_cb.....box6_cb All
    in the instance of: ComboBox - which I don't understand what that
    does.
    it does not seem to be retrieving any of the data. For each
    combo box:
    I have the the options people can choose form in "Labels" box
    under "Paramaters", nothing for "Data", Row Count is 8 and nothing
    for "Change Handler" which I don't know what it does.
    Can anyone please provide some help with telling me what
    "change handler" does, do I need the data for each combo box in the
    "Labels" parameter as well as the "Data" box, what an instance does
    (for combo boxes) and what I need to put in the actionscript for
    the submit button as well as do i need to put code in the
    actionscript for each combo box?
    The options people can choose from in the combo boxes are
    there when someone views the site.
    Can anyone please help me..I would greatly appriciate it.
    Thanks.

    If your hard drive can be detected and shows up as a drive letter in my computer but you can't access your files,then you can recover your data off it with data recovery software easily.This way is the easiest and the most inexpensive way to recover your data.If you bring it to a computer repair shop that is available for data recovery servise,they will cost you $500-1000 or more.Hmm, a lot of money.
    I managed to recover data from crashed hard drive with Tenorshare Data Recovery.If needed,you can download it and scan your hard drive for free to preview whether your data can be recovered.It will show you thumbnails for recoverable pictures.

  • Problem with combo boxes and the reset button in certain situations

    Hi Everyone,
    i have a problem to make the reset-button function properly in an what-if analysis dashboard.
    The dashboard uses two combo boxes that are not visible at the same time. In my application the second combo box only appears when a dedicated menu (label based menu button) has been activated.
    So i have combo box 1 when menu A is active an dand combo box 2 when menu 2 is active.
    After starting the dashboard initial values are fine. If you then directly change to menu 2 (seeing combo box 2 with
    the correct default value) and press the reset button, the dashboard returns to the initial view, showing
    the menu 1 with the correct default value. If you now switch back  to menu 2, you will see, that the combo box 2
    is empty (i.e. nothing selected).
    I also tracked the destination cells for the combo box value results as well as the source cells for the "selected item" and the
    destination cells for the "Insert Selected Item". All this values seem to be correct. Therefore i assume that
    this is an issue of event handling. Maybe the combo box 2 does not refresh its selected value because it is already
    invisible when the values are restored.
    This case can easily be simulated by placing two combo boxes and a push button (that changes the visibility of
    the combo boxes) and the reset button on the canvas.
    Maybe someone can help. I am able to provide a test xlf, if neccessary.
    Thanks,
    Oliver
    P.S. I am using Xcelsius SP4 (Version 5.4.0.0)

    Hello Debjit_Singha_86,
    thank you for your support. At the moment i have the following setting:
    label based menu
    - General: Insertion Type "value" from a list of ID's for the menu-items to a dedicated cell (current menu ID, say tab1!$A$1)
    - Behavior: Selected item (position) fixted to item 1
    hidden combo box
    - General: Insertion Type "position" to a dedicated cell with the current choice (say tab1!$B$1)
    - Behavior: Selected item (position) to the same cell (tab1!$B$1)
    Can you give me a hint on how to connect the two components according to your solution, so that the label based menu sets the default for the hidden combox box only in case, that the reset button is pressed?
    Thanks,
    Oliver

  • Problem w/"combo boxes" cause the user to double click for the dropdown menu, but not for everyone.

    I have created a form with Adobe Acrobad Pro 9.
    There are a few "drop-down" boxes for people to choose options from.  I created them with the "Combo box" option.  They work perfectly fine on my laptop (Lenovo T500 windows 7, with all updates up to date.)  I sent the file to another exact same computer and that's when the problem came up.  When you click on the drop-down, the list will quickly appear and then disappear.  Then if you click it again it will stay open so you can choose your option.  However this only happens on "some" computers but not everyone's.  I emailed the exact same form out to other people in my office and they do not have any problems with the form.  There is no need to double click the drop down, it will just open up properly for them.
    Has anyone come across this? And if so, is there maybe a setting on these specific laptops that is preventing the "combo box" to not work properly?  I need to use this specific laptop as a "Kiosk" like a "check out" station for users to fill out the form to check out equipment.  I will be running in Reader so people can not make changes to the form.  (both the Acrobat Pro 9 version and the (most up to date) Reader version of the PDF form does the same "double-click" problem)  I need a date drop down and an equipment type drop down.
    Any suggestions would be greatly appreciated !
    Thanks !

    I've got this kind of problem with a form of mine (designed with LCD) :
    - combo boxes with font-color changing event handlers on :enter
    - on Acrobat 9 Pro : no problem
    - on Reader 8.3 :
          - first click seems to execute the event handler but stops the combo's opening
          - second click does open the combo
    Do you have event handlers on combo:enter ?
    Could the difference between comps where it works and comps where it doesn't be Acrobat's version ?

  • How to populate the combo boxes that are created dynamically in jsp

    Hi,
    I am using JSP.
    I am creating combo boxes dynamically (based on the num selected by the user). These dynamically created combo boxes need to have A-Z as options (each box) . Now, when the user chooses the option A in any of the combo-boxes,the rest should not have this option. so on..
    how do i achieve this.Kindly help.

    You'll need to use JavaScript...I have a complicated example and a simple example, however, I cannot really understand the complex example but I know how it works. The looping is too complex for me.
    First you'll need to populate a server side variable...depending on how often the data is updated you may want this to run each time a new session is created...this example is run each time Tomcat is started and the application context is initialized:
    package kms.web;
    // Servlet imports
    import javax.servlet.ServletContextListener;
    import javax.servlet.ServletContextEvent;
    import javax.servlet.ServletContext;
    // utility imports
    import java.util.Map;
    // domain imports
    import kms.domain.LocationService;
    import kms.domain.DeptService;
    import kms.domain.PatentService;
    * This listenter is used to initialize
    * the Maps of Locations, Patents & Depts used to populate
    * pulldown lists in JSPs
    public class InitializeData implements ServletContextListener {
        * This method creates the Maps.
       public void contextInitialized(ServletContextEvent sce) {
          ServletContext context = sce.getServletContext();
          LocationService lServ = new LocationService();
          // Create the Maps
          Map campuses = lServ.getCampuses();
          Map buildings = lServ.getBuildings();
          Map floors = lServ.getFloors();
          Map locs = lServ.getLocations();
          // And store them in the "context" (application) scope
          context.setAttribute("campuses", campuses);
          context.setAttribute("buildings", buildings);
          context.setAttribute("floors", floors);
          context.setAttribute("locs", locs);
          DeptService dServ = new DeptService();
          Map depts = dServ.getDepts();
          context.setAttribute("depts", depts);
          PatentService pServ = new PatentService();
          Map patents = pServ.getPatents();
          context.setAttribute("patents", patents);
          //I did this one myself
    /*    CodeService cServ = new CodeService();
          Map masterMks = cServ.getCodes();
          context.setAttribute("masterMks", masterMks);
        * This method is necessary for interface.
       public void contextDestroyed(ServletContextEvent sce) {
       // I have no clue what the heck this is for???
       // Let me know if you do!
    }So now we travel into the PatentService method called 'getPatents();' which in turn calls a PatentDAO method
    Map patents = pServ.getPatents();
    Below is the code for the PatentService object:
    package kms.domain;
    import kms.util.ObjectNotFoundException;
    import java.util.*;
    * This object performs a variety of dept services, like retrieving
    * a dept object from the database, or creating a new dept object.
    public class PatentService {
       * The internal Data Access Object used for database CRUD operations.
      private PatentDAO patentDAO;
       * This constructor creates a Dept Service object.
      public PatentService() {
        patentDAO = new PatentDAO();
    public Map getPatents() {
          Map patents = null;
          try {
            patents = patentDAO.retrieveAll();
          // If the dept object does not exist, simply return null
          } catch (ObjectNotFoundException onfe) {
            patents = null;
          return patents;
    }It may be useful for you to see the code of the Patent class:
    package kms.domain;
    /*** This domain object represents a dept.
    public class Patent implements java.io.Serializable {
      private int codeGgm;
      private String name = "";
      private String description = "";
      private int creator;
      private String creationDate = "";
      private int used;
       * This is the full constructor.
      public Patent(int codeGgm, String name, String desc, int creator, String creationDate, int used) {
        this.codeGgm = codeGgm;
        this.name = name;
        this.description = desc;
        this.creator = creator;
        this.creationDate = creationDate;
        this.used = used;
      public Patent() { }
      public int getCodeGgm() {
          return codeGgm;
      public void setCodeGgm(int codeGgm) {
           this.codeGgm = codeGgm;
      public String getName() {
        return name;
      public void setName(String name) {
          this.name = name;
      public String getDesc() {
        return description;
      public void setDesc(String desc) {
          this.description = desc;
      public int getCreator() {
          return creator;
      public void setCreator(int creator) {
             this.creator = creator;
      public String getCreationDate() {
          return creationDate;
      public void setCreationDate(String creationDate) {
             this.creationDate = creationDate;
      public int getUsed() {
           return used;
      public void setUsed(int used){
           this.used = used;
    }And here is the Database table which stores the Patents:
    DESC PATENT:
    CODE_GGM NUMBER(3)
    NAME VARCHAR2(15)
    DESCRIPTION VARCHAR2(250)
    CREATOR NUMBER(10)
    CREATION_DATE DATE
    USED NUMBER(1)
    So, we then travel into the code of the PatentDAO to see how the DAO object executes the DB query to get all of the Data we need for the select list:
    package kms.domain;
    import javax.naming.*;
    import javax.sql.*;
    import java.util.*;
    import java.sql.*;
    import kms.util.*;
    * This Data Access Object performs database operations on Patent objects.
    class PatentDAO {
       * This constructor creates a Patent DAO object.
       * Keep this package-private, so no other classes have access
    PatentDAO() {
    * This method returns a Map of all the Dept names
    * The key is the Dept id
    Map retrieveAll()
           throws ObjectNotFoundException {
          Connection connection = null;
          ResultSet results = null;
          // Create the query statement
          PreparedStatement query_stmt = null;
          try {
            // Get a database connection
          Context initContext = new InitialContext();
           DataSource ds = (DataSource)initContext.lookup("java:/comp/env/jdbc/keymanOracle");
           connection = ds.getConnection();
            // Create SQL SELECT statement
            query_stmt = connection.prepareStatement(RETRIEVE_ALL_NAMES);
            results = query_stmt.executeQuery();
            int num_of_rows = 0;
          Map patents = new TreeMap();
             // Iterator over the query results
            while ( results.next() ) {
                patents.put(new Integer(results.getInt("code_ggm")), results.getString("name"));
             if ( patents != null ) {
                      return patents;
                    } else {
                      throw new ObjectNotFoundException("patent");
           // Handle any SQL errors
         } catch (SQLException se) {
            se.printStackTrace();
           throw new RuntimeException("A database error occured. " + se.getMessage());
        } catch (NamingException se) {
          throw new RuntimeException("A JNDI error occured. " + se.getMessage());
          // Clean up JDBC resources
          } finally {
            if ( results != null ) {
              try { results.close(); }
              catch (SQLException se) { se.printStackTrace(System.err); }
            if ( query_stmt != null ) {
              try { query_stmt.close(); }
              catch (SQLException se) { se.printStackTrace(System.err); }
            if ( connection != null ) {
              try { connection.close(); }
              catch (Exception e) { e.printStackTrace(System.err); }
    private static final String RETRIEVE_ALL_NAMES
          = "SELECT code_ggm, name FROM patent ";
    }Now when you wish to use the 'combo box' (also called select lists), you insert this code into your jsp:
    <TR>
    <%@ include file="../incl/patent.jsp" %>
    </TR>
    depending on how your files on your server are organized, the "../incl/patent.jsp"
    tells the container to look up one directory from where the main jsp is to find the 'patent.jsp' file in the 'incl' directory.
    I need some help creating multi-level select lists with JavaScript:
    Can anyone explain this code:
    <%@ page import="java.util.*,kms.domain.*" %>

    temp2.options[0].selected=true
    </script>
    This produces a related select list with 4 related lists by outputting JavaScript to the page being served. It works the same way as the first example that I describe but I don't understand the looping...maybe someone could explain how to go from the single select list to a double and/or triple level drill down?

  • LOV's in form combo box - how to change font size?

    Greetings:
    I've a table generated form (custom vs. tabular), with a combo-box field that fills with a LOV's that has as it's visible data, a rather long concatenated string. Therefore, this field makes the entire form rather wide when the LOV's contains a long string (as returned from the SQL that gathers the data).
    I've tried using the FONT tag in the 2nd tab (Form wizard) for custom layouts; that didn't work.
    Anyone have ideas for decreasing the font size of the LOV's? Else, I'll have to leave-out some of the info concatenated on that string.
    As always, thanks for you continued guidance and support...

    Hi,
    Changing the font size and other properties like font color, width, height, etc.. of the form elements can be achieved by using Cascading Style Sheet (CSS).
    It cannot be changed using <FONT> tag.
    In Portal, one can add the CSS attribute to the HTML tags in the custom layout of the form. But adding the CSS attribute to FORM elements (Input, select..)is not possible through Form wizards.
    However, this can be achieved by creating a form through the Dynamic Page. In this case you have to define your whole form.
    To know more about CSS you can visit: http://www.mako4css.com

  • Determine the best width for ListCellRenderer - Multi-column combo box

    Currently, I am having a multi column combo box. In order for the column to align properly during show popup, I use box layout to do so. However, the short coming for box layout is that, the size for each column is fixed. This makes me have a difficulty, when I have a long string to be displayed. The problem is shown through the following screen shoot.
    http://i.imgur.com/4Nfc6.png
    This is because in 2nd column,
    1) All the 3 rows must be in same size so that they are aligned.
    2) But 1st row and 2nd row cell renderer, do not know 3rd row is holding such a long string.
    The code (2 files) to demo this problem is as follow. Is there any way the size of the cell will be adjusted automatically? Yet, all the row will be aligned properly.

    Are these two lines intentionally or is it just a mismatch?
    jLabel2.setMaximumSize(new java.awt.Dimension(100, 14));
    jLabel2.setMinimumSize(new java.awt.Dimension(200, 14));
    2) But 1st row and 2nd row cell renderer, do not know 3rd row is holding such a long string.There is only one cell renderer for all rows, so no need for the rows to know each other.
    To calculate the exact maximum width of column two, you have to check each entry.
    If you can do this BEFORE creating the combo, you could do this in a loop similar to this pseudo code
    FontMetrics fm= jComboBox1.getFontMetrics(jComboBox1.getFont());
    foreach (column2String) {
      int length= fm.stringWidth(column2String);
      if (length>max) max= length;
    }Now you have a max value to dimension jLabel2 in your renderer.
    If you don't fill your combo in one go, but rather at runtime, you have to check at each
    jComboBox1.addItem(...)
    whether the string for label2 is extending the current max, redefine max, and repaint the combo.
    This second approach I haven't done so far, but that's how I would try.

  • Combo Box items missing

    Hi,
    I'm new to ADF and have a few basic questions.
    1)From a View Object in the Data Control Palette I dragged and dropped an attribute as Combo Box. When I run the panel no items are shown, although data is available at the database. I actually expected that ADF handels the item adding in a combo box. Is some coding really needed or what is the standard way of doing that?
    2) How can one handle dynamic displaying in combo boxes (one item selected in one box defines the items of the next one).
    Thanks.

    Hello Frank,
    thank you for your replay. Problem 1) is solved, I just had to pick the View Object and drop it as a combo box instead of the attribute itself.
    Regarding 2) I did it as follows:
    - In a JClient application I created Entity Object from two tables with 1:n relationship
    - Generated views from these EO's
    - Added those vews to my application module
    - Dragged and droppped both views in a JPanel as combo boxes
    Now what has to be reached is that by selecting one item from the first (master) combo box the items shown on the following one are only those that correspond to the Foreign Key relation.
    Thanks again

  • Combo Box Clearing

    The combo box on my form has a list of valid values. When the form loads the combo is in a state where no value is selected.
    Once I have selected a value in the combo and added a record I want to clear the combo box for the next item to be added.
    The combo box retains the previous entry and there doesn't seem to be a way to put it in a null or non-selected state.
    Is there a way to set a combo box to a state where none of the valid values are selected, once one has been selected.
    Thanks for any help.

    thanks Dilip and Vishnu,
    I added the following to handle the case where the "" value already existed and to remove it if it was added just to clear the combo.
    try
    ddlStatus.Select("", SAPbouiCOM.BoSearchKey.psk_ByDescription)
    catch
    ddlStatus.ValidValues.Add("", "")
    ddlStatus.Select(ddlStatus.ValidValues.Count - 1, SAPbouiCOM.BoSearchKey.psk_Index)
    ddlStatus.ValidValues.Remove(ddlStatus.ValidValues.Count - 1, SAPbouiCOM.BoSearchKey.psk_Index)
    end try
