Dynamically Populating Drop Down Lists
Hi,
I am trying to dynamically populate a drop down list on a form based on a selection in another drop down list. I have read the help file "To dynamically populate a second field after populating the first" which goes through an example, however I cannot get this example to work for me.
I know that the best way to do it is to create an xml file and connect the form to this file. I am new to programming in xml but have had some experience in other forms. The code that I have (from the help page) looks like this;
<?xml version="1.0" encoding="UTF-8"?>
<MyData>
<country/>
<countries>
<item uiname="United States" token="US"/>
<item uiname="Vietnam" token="SRV"/>
</countries>
<state/>
<US>
<item>California</item>
<item>New York</item>
<item>Texas</item>
</US>
<SRV>
<item>An Giang</item>
<item>Bac Giang</item>
<item>Bac Kan</item>
</SRV>
</MyData>
I have then followed the instructions on the page, and am unable to populate either field on my form. Perhaps there is something wrong with my code? Or any other suggestions would be greatly appreciated!
ThanksHi Paul,
I have another question,
I would now like to populate a third drop down menu based on the selection in the second one, however my code is going wrong somewhere as now when I put in the first 2 drop down lists, nothing appears in the second one. ie, the first drop down list I link to countries, and the second to state, as I did with the previous file, but now, when I preview it, I can choose a country, but nothing comes up in state. When I set the first drop down box to countries, I have to specify that I want it to show the uiname, but I can't do that with the second one when I select state using the XML file below, nothing is shown. Where am I going wrong?
<MyData>
<Country/>
<countries>
<item uiname="United States" token="US"/>
<item uiname="Vietnam" token="SRV"/>
</countries>
<state/>
<US>
<item uiname="California" token="CA"/>

Drop Down Menu selection query for recordset.
I am looking to utilize a dynamic drop down menu to query a recordset...I am using Colfusion to import an MS Access database that contains the following fields: "Model Date", "Name", "Points" and "Target". Each time the database updates, the "Model Date" field contains the date and time the model was run. I have figured out how to create a dynamic drop down using SELECT DISTINCT "model date" and have also figured out how to create the dynamic recordset to be displayed showing the "Name", "Points" and "Target" data.
I want the user to select the "Model Date" from the drop down, hit a submit button and then have the appropriate "Name", "Points" and "Target" data queried and shown below.
The query should take the selection from the "model date" dropdown and then query the "name", "points" and "target" fields for that particular "model date"
I admit my knowledge of SQL and Coldfusion is not the best, but it seems like this is a somewhat simple task and I am just missing one or two pieces of the cog to put it all together.
The database basically looks like this:
Model Date...........Name..........Points........Target
8/1/2010 08:00......John Doe.....1,250.........5.55%
8/1/2010 08:00......Jane Doe.....850............2.35%
8/1/2010 08:00......Bill Smith....11,832........-123.23%
8/2/2010 09:02......John Doe.....1,323.........6.67%
8/2/2010 09:02......Jane Doe.....1,001.........3.21%
8/2/2010 09:02......Bill Smith....10,235........-110.26%
The dropdown will only show the "model dates"
8/1/2010 08:00
8/2/2010 09:02
For example, if 8/1/2010 08:00 was selected from the dropdown, I want the following displayed:
Name..................Points...................Target
John Doe.............1,250....................5.55%
Jane Doe.............850.......................2.35%
Bill Smith............11,832...................-123.23%
Any help or suggestions would be greatly appreciated!!!
Thanks,
MikeMy second paragraph talks about just displaying the filtered data, so I'm assuming that's what you're looking for, but still not quite sure based on what the other responses are.
But I head on anyway -
On your first page, make note of the instance name of your drop down menu, such as "ModelDate". Make sure it's in a Form and set the form action to the page where you want to display your data, set the form action to POST.
On the results page, create a table with cells for each of the data elements you want to display. Create a recordset which you can do in Simple mode. Leave it at select all, and set the filter drop down to the database field which contains your Model Date. In the box to the right, select "=". the next dropdown selct "Form Variable" and the variable name type in the instance name of the drop down on the first page.
I may not have the terminology right, doing it from memory.
From the data bindings tab, expand your recordset and locate each of the database fields you want to display. Drag each one to the table cell on the page where you want it displayed. The table cells have to be in a linear row.
Now, select the table row buy selecting the TR tag in the tags just above the properties panel. In the server behaviors tab, select repeat region and "All Records"

Self populating drop down lists.
Is there any tutorials or information to do a self populating
drop down list
in CF?
I assume you would have the form post back to its self using
a IsDefined for
each drop down step. Drop Down 1 (DD1) is selected and that
posts back to
the same page and causes the DD2 to run a SQL query based on
DD1's choice
and you repeat the process until the final DD is selected.
Is this correct and where can I find a good tutorial?
Thanks

Dynamically create drop down box with JSP
Hi,
I hope this is not a repeat post, I have search the forum and a posting has not jumped out at me. I am making a jsp that dynamically constructs a custom SQL query.
I have a number of text boxes with an id, my jsp page calls a servlet, the servlet reads the contorl id and the value to build the query - this works great. However, there's a large text input box which receives a number of extra conditions - this text box receives the input in the following format:
searchAttributeName1,searchAttributeValue1;searchAttributeName2,searchAttributeValue2
This is functional, however, it's a bit rubbish as the user has to know the special recognised attributeNames. What I would like to have is some sort of criteria control. This would consist of a drop down box populated from the servlet, a text input for the value and a button to add another criteria control. so the user could build up the number of query criteria. The drop down box ensures they cannot select the wrong keyword, pressing the add criteria button adds a new drop down box and text box pair to the screen.
An example of this I recently saw was at Intel's jobs search web site https://jobs.intel.com/jobs/jobs.iccw - see that for example.
Has anyone got any ideas on how to achieve this? I initially thought use jsp scripting (there is no restriction against this) but I need to use javascript I'm guessing as the button click triggers adding a new combo box. Another idea was to use styles and tables to hide the other drop down boxes but this seems like a real hack that I'd like to avoid. I can do with with .NET i hope java can deliver!
Any ideas are much appreciated - I am a novice with java web development so please, any examples thoroughly explain (no need to explain populating the drop down box - there seem to be plenty of posts on this).
Thanks for any help or ideas on this issue -Gina,
Here is some sample code for using a ComboBox in a JSP from an EditCurrentRecord bean. This particular example uses a query, you can also populate combo boxes, list boxes, radio buttons and checkboxes from a static list. See the JavaDocs for the EditCurrentRecord bean.
<jsp:useBean id="RowEditor" class="oracle.jbo.html.databeans.EditCurrentRecord" scope="request">
<%
RowEditor.initialize(application, session , request, response, out, "wt_bc_WT_bcModule.WalkthroughEngineSlidesView");
RowEditor.setTargetUrl("WalkthroughEngineSlidesView_SubmitInsertForm.jsp");
RowEditor.createNewRow();
RowEditor.setReleaseApplicationResources(true);
RowEditor.useComboBox("Presname","select pres_name,pres_name from wt_info","PRES_NAME","PRES_NAME");
RowEditor.render();
%>
</jsp:useBean>

Populating Drop-down List in Interactive Forms for Java
Hi,all
I need to populate a drop-down list in Interactive Form.
I tried to do it by using Dynamic Properties of the drop-down
list,but didn't give nothing.At the same time I have successfully
populated a simple drop-down list(on webdynpro view),which I
replaced near my InteractiveForm.
What may be the problem?
Regards,
MichaelUse the DDL from the Web Dynpro pallette. Bind the same/ similar attribute of the DDL you used in the web Dynpro view in the interactive form also... this should work..
Thanks and Regards,

JSF & IFrames to dynamically load drop down lists
I have a drop down list (DDL) whose content is dependant on another DDL. I have implemented this fine using JSF using the following jsp:
<h:outputLabel for="selectRegion">
<h:outputText value="Region"/>
</h:outputLabel>
<h:selectOneMenu id="selectRegion" validator="#{LocationBean.validateDDL}" value="#{LocationBean.region}" valueChangeListener="#{LocationBean.changeRegion}" onchange="submit();">
<f:selectItems value="#{LocationBean.regions}"/>
</h:selectOneMenu>
<f:verbatim>
<iframe id="regionFrame" name="regionFrame" style="width:0px;height:0px;border:0px"></iframe>
</f:verbatim>
<h:message for="selectRegion"/>
<h:outputLabel for="selectDistrict">
<h:outputText value="District"/>
</h:outputLabel>
<h:selectOneMenu id="selectDistrict" validator="#{LocationBean.validateDDL}" value="#{LocationBean.district}" onchange="submit();">
<f:selectItems value="#{LocationBean.districts}"/>
</h:selectOneMenu>
<h:message for="selectDistrict"/>When selecting a region, the onChange="submit();" resubmits the entire page and the valueChangeListener="#{LocationBean.changeRegion}" is triggered which updates the district DDL.'s options.
Resubmitting and retrieving the entire page contents is an expensive task, so I would like to use iframes/javascript to dynamically reload the second DDL without reloading everything else.
Can this be done in conjunction with the JSF framework, or does JSF require a full page submit and retrieval in order to go through the JSF lifecycle?Any ideas?
I've got a bad feeling the problem is that a hidden iframe being populated using a get method such as
"directorate.jsp?directorateId=1" won't work because JSF doesn't support the html get method.
Any other ways of reloading just a single portion of the page anyone knows about?

How to add drop down list for query manager report in sap business one
Hi Every one,
I need drop down list for parameter selection in sap business one Query Manager.I have two Parameters 'Sales Order','Invoice'.
Please suggest.
Thanks and Regards
DEVHi,
you need to use this :
/*select from [dbo].[OINV] T2*/
DECLARE @Invoice varchar(100)
/*where*/
set @Invoice =/* T2.DocNum */N'[%2]'
you can change the tables and the parameter number but you have to write it exactly that way.
when you run the query within the SBO you will get list of objects ( in this case list of invoices)
hope it was helpful

Error while populating drop down list with values from a database
Hi all,
I have a JSP page with a drop down list that is to be populated with values from a database.
This is the code in my JSP file:
<!-- Form for picking the floor -->
<!-- Get the available floors -->
<% ArrayList<Integer> floornumbers = dataManager.getAllFloorNumbers();
Iterator<Integer> iterator = floornumbers.iterator(); %>
<!-- Create the form for users to select the floor -->
<form id="floorselectionform">
<input type="hidden" name="action" value="floorselected"/> <!-- Guides the servlet to redirect to the appropriate page -->
Select floor | <select name="floorselector" id="floorselector">
<% while (iterator.hasNext()) { %>
<option value="<%=iterator.next().intValue()%>"> <%=iterator.next().intValue()%> </option>
<% } %>
</select>
<input type="submit" value="Go!"/>
</form> The DataManager.java class simply forwards this to its respective Peer class, which has the code shown below:
package seatplanner.model;
import java.sql.Connection;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
import java.util.ArrayList;
/* This class handles all floor operations */
public class FloorPeer
/* This method returns all the floor numbers */
public static ArrayList<Integer> getAllFloorNumbers(DataManager dataManager) {
ArrayList<Integer> floornumbers = new ArrayList<Integer>();
Connection connection = dataManager.getConnection();
if (connection != null) {
try {
Statement s = connection.createStatement();
String sql = "select ID from floor order by ID asc";
try {
ResultSet rs = s.executeQuery(sql);
try {
while (rs.next()) {
floornumbers.add(rs.getInt(1));
finally { rs.close(); }
finally {s.close(); }
catch (SQLException e) {
System.out.println("Could not get floor numbers: " + e.getMessage());
finally {
dataManager.putConnection(connection);
return floornumbers;
} The classes compile properly, but when I load this page up in Tomcat it just freezes and does not load the form. I tested the DB connection and it works fine.
What am I doing wrong in the JSP code?
Thanks for the help in advance.
UPDATE: I commented out the form, and added <%=floornumbers.size()%> right above the commented code to check if the ArrayList is indeed getting populated with the values from the database (the values are of type integer in the database). The page still freezes like before. I'm puzzled now :confused: .Wrong usage of Iterator.
<!-- Form for picking the floor -->
<!-- Get the available floors -->
<% ArrayList<Integer> floornumbers = dataManager.getAllFloorNumbers();
Iterator<Integer> iterator = floornumbers.iterator(); %>
<!-- Create the form for users to select the floor -->
<form id="floorselectionform">
<input type="hidden" name="action" value="floorselected"/> <!-- Guides the servlet to redirect to the appropriate page -->
Select floor | <select name="floorselector" id="floorselector">
<% while (iterator.hasNext()) {
Integer inte = iterator.next();
%>
<option value="<%=inte.intValue()%>"><%=inte.intValue()%></option>
<% } %>
</select>
<input type="submit" value="Go!"/>
</form>or make use of enhanced loop as you are already using J2SE 5.0+ for avoiding confusions.
<!-- Form for picking the floor -->
<!-- Get the available floors -->
<% ArrayList<Integer> floornumbers = dataManager.getAllFloorNumbers(); %>
<!-- Create the form for users to select the floor -->
<form id="floorselectionform">
<input type="hidden" name="action" value="floorselected"/> <!-- Guides the servlet to redirect to the appropriate page -->
Select floor | <select name="floorselector" id="floorselector">
<% for(Integer inte:floornumbers) {%>
<option value="<%=inte.intValue()%>"><%=inte.intValue()%></option>
<%}%>
</select>
<input type="submit" value="Go!"/>
</form>and a lot better thing would be making usage of basic Taglib provided with JSTL spec or struts spec which make life easier and simple.
something like usage of <c:forEach/> or <logic:iterate/> would be lot better without writing a single scriptlet code.
Hope that might help :)

Drop Down List in Query Selection Screen Takes Long Time.
I open a report, refresh the query and get a selection screen. But when clicked on the drop down list it takes 4- 5 mins for displaying the drop down options.
How can I speed up the displaying of drop down list in selection screen?
Could any one please help regarding the setting to enable this?
Thanks.Hi,
I guess there is a setting to look up the master data tables or use the dimension,which would speed up the time that it takes to display the drop down selections
Do you have any idea about the setting?
Thanks. -

you can do these settings in info object level.
Go to info object : Select Business Explorer Tab
Option is : Query Execution Filter Val. Selectn : here you can specify info provider.
Plz assign points if it is useful.

I am working on a form for my company. I am trying to populate the drop down box list from entries in a previous text field. For example I have a text field that directs users to type in a list of items. I want these items to then automatically generate into a drop box field. I have researched and tried for days with no success. The closest I have come is setting the drop box value to the text field but all this does is copy the list exactly into the drop box visible field...it does not set the values as selectable options. Any help is greatly appreciated!

Populating drop-down box from Server XML
Hello all,
I'm working on a REST - Lightroom interface, which I'm going to document as expose as a way for anyone to upload pictures to their site.
Anyway, I need to populate a drop-down with the story names and ids from this XML. Any ideas? I'm a top actionscripter/ruby/etc, but not too familiar with Lua. Looks good though.

Hope someone can help :)Hi there,
I'm also facing an identical problem and would also like the solution. I've thought about using JavaScript in conjunction with JSP to populate the second drop down box dynamically. But first I need to retrieve the values in the first drop down box from a database and subsequently the 2nd drop down box - I'm thinking that a for loop needs to be used somehow. amishpg, I will let you know If I'm successful.
