Using Combo box at the backend

Hi,
I am using combo box at the backend to filter rows to a particular destination.
The problem is the labels are going to populate at the runtime and the selection of item in combo box is also going to populate at the run time. I have an icon which inserts eg: country in a cell, then this cells is used by combo box as a item selection(label) to filter rows from source. But unfortunately the comb box is not selecting any value i.e no item is selected dynamically. But if i manually drill down it is working but the label is not changing dynamically based on the changes in label by icon.
For eg my data:
Country and profit populate at run time
Country          Profit
India               5000
Germany        4000
Now i have icon which selects country (hard coded in excel) upon clicking the mouse on it and inserts in A1 suppose the value hardcoded is "India". Now this A1 is used as a "selected item" for combo box. the source to combo box is the above country and profit which populates at run time.
Now when i execute the dashboard. The value is inserted in A1 after clicking the icon but it is not picked up by combo box as "item selected" and hence combo box does not filter any data.
Can any pls help.
Thank you. I will award full points for correct solution.

Hi Monammed,
The said functionality should work. Please check your logic one more time. Also, try using some spreadsheet components mapped to the cells in question and understand how the data is flowing during run-time. This will help you test things. Delete spreadsheets when you are done with identifying the issue.
Lets check the combo box mapping one more time : Map the source of the combo to the entire range; labels in the combo box ONLY to the country column in the source range(typically this may be the left most column in the range); selected item should be mapped to the cell that has the destination for the icon and the type for default selection may be dynamic. Well, if there is any hard-coding of values involved anywhere, do check the spellings and other trivial things.
Do let me know if this was helpful and if you need any more help.

Locating on a location on GMap using combo box using SDK

Hi All,
I have a requirement to locate a city on google map using combo box. I want name of cities to appear in combo box and on selecting a city, map should be able to locate that city. This combo box will be visible on map itself. Combo box can be a component of either Xcelsius or Flex Builder.

How to use check box in flash 8?

How to use check box in flash 8?

If you want it to happen when someone clicks the checkbox, then you need to add a listener for that event.
var cbListener:Object = new Object();
cbListener.click = function (evt:Object) {
if (cb.selected) {
gotoAndStop(2);
cb.addEventListener("click", cbListener);
(Note: "cb" and "cbListener" are names that were made up for this example. They could be anything you want to name them)

How validate a combo box generated for a selectOne on javascript

Hi!!
I have a question!
i need how validate a combo box on javascript if this is generated by selectOne
for example:
<tr>
<td width="150px"><b>Cantidad a elegir:</b></td>
<td><f:selectOne att='idisponibilidad.cantidadElegir' type='combo'/></td>
</tr>
this is an form and this generates in the name of the select:
<select name="$FO$idisponibilidad.cantidadElegir">
<option value="0">..</option>
<option value="4">..</option>
</select>
but now I try to do this:
document.form.$FO$idisponibilidad.cantidadElegir.value
and obviously does not work!!!
someone knows how to validate
Thanks!!!

Taking Mark's Code .. add an id
<select id="personGender" <f:fieldName att="person.gender"/>>
<c:forEach var="gender" begin="0" items="${genders}" varStatus="status">
<c:choose>
<c:when test="${person.gender == gender}">
<option value="<c:out value="${gender}"/>" selected="true"><c:out value="${gender}"/></option>
</c:when>
<c:otherwise>
<option value="<c:out value="${gender}"/>"><c:out value="${gender}"/></option>
</c:otherwise>
</c:choose>
</c:forEach>
</select>
Add an id to above code. In your submit button write a function on onclick event .. like onclick="submitForm()"
Write the functions as :
function submitForm(){
     if(validateFileds()){
document.<your form id>.submit();
function validateFields(){
if (isEmptyCombo ('personGender')) {
               alert ( "'Selecting a gender is mandatory" );
               focus('personGender');
               return false;
function isEmptyCombo (id) {
     var combo = document.getElementById(id);
     return combo != null && combo.options[combo.selectedIndex].value == "";
function focus (id) {
     if (document.getElementById(id)) document.getElementById(id).focus();

the brand old dependent combo issue..
as far as i know i could tell you for every two days a similar post is being posted here on the same thread..
you could have taken a look of them....
Anyways there are many ways of doing it....
In the days when XmlHttpRequest Object was not invented ppl used to achieve this using Hidden iframe and then updating parent frame dropdown by calling a javascript function onload of the page. or by auto refershing the page after saving the form state inside the scope of session.
However,using XmlHttpRequest Object (AJAX) nowdays is one of the smater ways of acheving tasks as these.
checkout one such examples where i've posted a similar example in the last reply

How to fill combo box with list of all SQL server

Ok, I know how to find all SQL servers that I need, I have code for that task, and I have Array of all servers.
My problem is ...
I made setup project and do a huge work, and in the end this task appear!
I used ORCA tool to change TextBox (A) template in visual studio (2008 by the way), and I transform first TextBox to ComboBox.
Now, the little part that I'am missing is how to fill this combo box with a result of my function for listin SQL servers?
Can I somehow send combobox object to myMethod:
private void FillCombo(ComboBox cmb)
// do the job
or
instanceOfThisCombo.Items.Add(listOfSQLServers);
please help me to solve this... thanksc#

Hi Valerij,
The ComboBox control in an MSI dialog uses the ComboBox table to populate the items in it. To get what you want, you need to update the ComboBox table in the MSI package with your application and run the MSI package. The following KB article describes how to dynamically populate a ListBox control in Windows Installer:
http://support.microsoft.com/kb/291329
This method introduced in the above KB article also applies to populating a ComboBox control in Windows Installer.
I don't think it's possible to run the application as a Custom Action from within the MSI package because the application will modify the content of the MSI package which is currently running. So you need to launch the MSI package from within your application after updating the ComboBox table. In short, when installing, just run your application which updates the ComboBox table and install the MSI package.
Hope this helps.
If you have any question, please feel free to let me know.
Sincerely,
Linda Liu

Using Combo box to create options

Hello,
I am using a Framegrabber to acquire my images from our custom made sensors. We have several models so I wrote several Drivers for each one. I have managed to use a combo box with the names of the sensors to select which driver is loaded into the IMAQ board. However, because the application is getting more and more complex, and because I want to have one universal application for all our sensors, I want to have the ability to select different options according to the driver that is selected. For example, if I select Sensor A, and I want to use the serial communication, I want the address of sensor A to be used in the VI. If I choose Sensor B, the values related to sensor B are to be chosen. I guess the idea is simple to implement using an If Statement in C or other languages, but I don't want to go through that mess, and I want to implement it with LabVIEW.
I could use a Case structure, but that only gives me two options. And I am not very good with Event structures and I do not know if I can use it for this. I also tried to use a local variable, but it would not let me change the values associated with the labels.
If you understood what I was trying to say, and have an idea, I would greatly appreciate your help. If you are interested in helping but need a visual illustration, I can put a quick VI together for you.
Thank you in advance,
Rami

Hi.
I think I am doing something wrong, but, maybe someone can quickly enlighten me.
The situation is this.
I have a combo box with about 65 values. I want to feed these into a case structure (to select a range of settings to use later on)
How do I get the values to also appear in the case headers? All I have is true and false..
My output of the combo box is a string, not a number. is that why I dont get the values automatically?
I've attached the combobox and a case structure.

Report error when using combo box and one text field is empty

I'm building an interactive pdf in adobe pro 9. My problem is the following: I have one text field where you can enter a numeric code and that is used to populate another text field when I choose an option on one combo box.For example: suppose I write the code 123 in the text field "A" and that the combo box has two options ("data" and "-"). When I select "-", another text field "B" is empty, while when I select "data" i populate the text field "B" using the code entered "A" with the text "data_123". In order to do this I use the standard javascript code in the Format>Custom tab of the combo-box.
My questions are:
- how can I prevent the pdf to proceed selecting an option in the combo box when the field "A" is empty?
- how can I update the field "B" every time that I change the text in "A"? I found that the text is "B" is updated only when I press the selection in the combo box.

You can set the combo box to read-only in the Validate event of the A field:
// Validate script for text field
getField("combo1").readonly = !event.value;
To update the value of B when A changes, you can expand the script above to something like:
// Validate script for text field
var f1 = getField("combo1");
var f2 = getField("B");
// If there is an entry in the A field...
if (event.value) {
    f1.readonly = false; // Make sure the combo box is activated
    f2.value = f1.value === "-" ? "" : "fa.value + event.value; // Update the value of field B
} else {
    f1.readonly = true; // Deactivate the combo box
    f2.value = f2.defaultValue; // Reset field B
You might also want to reset the combo box somewhere in there, but it's not clear to me when you would want to do that.

Iterating throw UDO records by using combo box

Hi all
i have a form with a matrix which is connected to UDO with master data and master data lines tables. i have a combo box which contains the Code values of the master data table.
when selecting a code value from the combo box i want the matrix to display the master data lines data which relates to the code value which was chosen in the combo box. i want to use the UDO mechanism for displaying the data so i don't want to query the dbdatasource which is bounded to the matrix.
question is how can i activate the UDO to display the relevant data to the code value which i chose in the combo box?
appreciate the help
Yoav

move the combo to the header level.
if the document is in find mode with correct data in the code field and u click find it will bring up the relevant data.

Use Combo Boxes and Datepart "m" and "y" to filter forms and reports

I am trying to build a Form to filter through Sales Order Records going back up to four years to find purchasing patterns of customers and to find more potential sales. I am using a simple main form, with 2 subforms joined on the Sales Representative
[accntrep], one which show current orders for a given month and the other orders from past months and years. I've got 3 combo boxes, 1 to select sales representative, 1 to select a month using date part and 1 to select a month. This would be very
flexible in easily searching any month in any year of the recordset. I know I will be using something like "DatePart("m",[Date])=2 And Year([Date])=Year(Date())-4" (Feb 2011) to filter my records, but I am having troubling writing
the procedure just right. I am using 2-column combo boxes 1 column for text i.e (April, May, June etc.) and a second for the Date Part Expression. I think I need to concatenate the values into the filter, but I cannot come up with exactly how to
get this done. Any ideas??
Thanks,
js

If there is any doubt in your mind then I will suggest a sanity debug trick; temporarily add 2 textboxes
in T1 put its control source: =ComboBoxNameMonth
in T2 put its control source: =ComboBoxNameYear
don't put what I typed - put in their actual control names for those 2 comboboxes
this way you can see what is actually the value of those combo boxes... depending on what they are bound to - those values may not be what you are expecting them to be.....obviously alter the properties of the comboboxes until they have the values they should
Am a little unclear on filtering your records in regard to how the data is not structured whether for example: Nov 2015 is in 2 separate fields or a single field like 11/2015 or what - not sure it is a true date field or possibly a text field...so
the next part of this depends on the data structure.
