Catching COMBO BOX item changed in VALIDATE event

Hi expert,
I need to catch the item changed event for a combo box.
below the code:
<B1Listener(BoEventTypes.et_VALIDATE, False)> _
Public Overridable Sub OnAfterValidate(ByVal pVal As ItemEvent)
Dim form As Form = B1Connections.theAppl.Forms().Item(pVal.FormUID)
Dim mt As Matrix = Form.Items.Item("Matrix_0").Specific
if (pVal.ColUID.Equals("TipoList") And pVal.ItemChanged) Then
end if
but pVal.ItemChanged is always equal to false even if I change the value selected in combo box.
can anyone help me?
Thanks in advance.
Best regards
Andrea

Hi Andrea,
you can also catch the Event through
pVal.EventType =SAPbouiCOM.BoEventTypes.et_COMBO_SELECT
through this event, you can perform you're reuqirement.

Calling a bean method on select of Combo box item

Hi
On select of Combo box item in a form, text fields in the same form should be populated
dynamically.Is it possible to call a bean method which does this,by calling onSelect() method
of combo box ?
Thanks in advance,
Sridevi

Uff, sorry!
I ment that you write some code for the "onSelect" event which sends a request to the server with the selected value: onSelect="self.location.href='<%= request.getRequestURI()%>?selectedVal= ' + this.selectedIndex;"

Creating a combo box to change graph type

Hello Gurus,
I need to create a combo box in a web page to change the graph type used. How would I go about to achieve this?
Thanks.

ceate the second combo box , at the palce where i will create the first combo boxAs i see .. u dont require two comboboxes in u r case just have to set the combobox with different ComboBoxModel each time u make a selection.
in listener event of the combobox change the model with setModel function. You can create new model by
combo1.setModel(new JComboBox(new Object[]{"opt1","opt2","opt3","opt4"}).getModel());

Combo Box Items

I am setting up a fillable form using adobe. I am trying to set a combo box values/items based on multiple fields within the form. For example, the first part of the form will have a user list employee names. I am trying to have the names entered appear as the options in the combo box. Any suggestions would be greatly appreciated.

Thanks for the info. Using the link, I was able to set the items by typing text in the script. I'm getting stuck on how to set the items to existing fields in the form. For example, I have a list of text fields "Name1","Name2",etc up to "Name10". I want to set the combo box to show the values intered in these fields but can't seem to get it to work. Any suggestions?
Thanks Again

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

How can i make 2 combo boxes as the same data source and group by each combo box items separately?

I have 2 combo boxes If I have data table like below
TableA
ID NAME
1 A
2 B
3 C
4 A
I make "TableA" as data source of "combobbox1" and "combobox2" like
combobox1.datasource = TableA
combobox1.displaymember = "ID"
combobox2.datasource = TableA
combobox2.displaymember = "Name"
I want when combobox2 select index at "A" , Combobox1 show only the items at ID = 1 And ID = 4
Thanks

This is not actually a question to be posted in SQL Server. Here is a link for ASP.NET forum.
http://forums.asp.net/
It looks like there is a filter that can be applied in .NET dataset and populate the results in your combobox1. You may get better help from .NET forums for this question.

How do you add a combo box item in Forte?

Okay how do I add items to a JComboBox using the Forte form editor.

String stuff = new String{"1", "2", "3", "4" };
I think you ment to make stuff an array of String.
In component inspector under Code Gneration
select post creation, select the ... box and type in
new JComboBox(stuff); or = new JComboBox(stuff);
might have to put the equal sign in there I forgetI did this and I am not getting any items dropped down.

When i change the value of a combo box using a property node it displays the value not the item label

I am using a combo box as a select list for text serial commands. I have items like "engineering", "GUI", and "Scan" for the commands "MDE", "MDN", and MDS respectively which i have input as the corresponding value in the combo box. so for example the label "engineering" has the value "MDE" in the combo box items list. when the Vi starts it needs to read the current value MDE, MDN, or MDS and then i want it to display on the front panel the item text corresponding to that command value.
To do this i have tried to read the serial command, ie MDS and then wire that to a "value" property of a property node of the combo-box, but instead of displaying the corresponding item label, "Scan", it displays the value "MDS" on the front panel instead. i want the front panel to use the label text when choosing and displaying but the block diagram to use the serial commands. Can this be done with a combo box? I'm trying to use a combo box so i can keep it all text and avoid having to build a case statement to convert enums or rings from a numerical value to the text command.
The correct text value is wired to the value property and it does exist in the combo-box. I have unchecked "values match items" and selected to not allow undefined values.

Don't use the value property node. Use the Text.Text property node. When creating the property node, select Text, then in the next pop-up box, select Text.

Action event automatically triggered for combo box

Hi all,
I am facing a typical event handling problem for combo box in Swing(Using Net Beans 5.0, jdk 1.4.2)
While adding items to combo box it is firing action event twice instead of once irrespective of no. of items added to it.
For eg if there are 1 or more than 1 item added to combo box it is triggerring action event twice(one just after when first item is added and one again when rest all items are added)
and if there is no item then also it is triggering once.
Can you please help me out.
Thanks

Hi Dylan2412,
According to your description, you'd like to pass the ComboBox.Text to the second form's TextBox.
In Form1:
private void button1_Click(object sender, EventArgs e)
Form2 f2 = new Form2(this.comboBox1.Text); //pass the comboBox1.Text
f2.Show();
In Form2:
public Form2(string s) //get the string;
InitializeComponent();
this.textBox1.Text = s;
You could get the comBoBox refer to this sample above.
If you have any other concern regarding this issue, please feel free to let me know.

Layer/OCG Visibility based on Combo Box Selection

Hello,
I'm VERY new to javascript, so please bear with me. I have a combo box with multiple selections. For some selections, I would like a separate OCG layer to appear, and with other selections that same layer to disappear.
For example:
ComboBox1: A, B, C
Layer 1 default: hidden
A - toggle layer 1: hidden
B - toggle layer 2: hidden
C - toggle layer 3: visible
I have seen the javascripting involved turning layers on/off with buttons, but I'm having some difficultly with the combo box.
Thanks!
Mike

The code would be much the same as with buttons. Use the Validate event of the combo box to get the selected value (event.value) and show/hide the appropriate OCGs. If the combo box items have export values, you'd use the Keystroke event so you can get the export value of the selected item via the event.changeEx property: http://livedocs.adobe.com/acrobat_sdk/9.1/Acrobat9_1_HTMLHelp/JS_API_AcroJS.88.607.html

Combo box help

ok i have 3 combo boxs - name, id, pic
the first combo box name determines the values of the other comboboxes. the id combo box value changes successfully
but when i try and change the value of the pic combobox i get
an out of bounds error. can anyone suggest some advice?
String name = namecombo.getSelectedItem().toString();
nametextfield.setText(name);
idcombo.setSelectedIndex(namecombo.getSelectedIndex());
// piccombo.setSelectedIndex(namecombo.getSelectedIndex());
//the line above produces the error

no unfortunately they have the same number of items.
i have tried everythingNo, they don't, if they did, then there wouldn't be an OOB error. Try this:
String name = namecombo.getSelectedItem().toString();
nametextfield.setText(name);
idcombo.setSelectedIndex(namecombo.getSelectedIndex());
System.out.println(namecombo.getItemCount());
System.out.println(idcombo.getItemCount());

Combo Box Selected Data

I have a combo box called class_cb, I am trying to use the
combo box in a maths formula.
I am trying to set that if the active selected combo box data
= 1 then a text area = given number, if data = 2 then ....
I can get flash to recognise the change i just can't seem to
get the statement
"if selected combo box data = 1 then text area = 5" to work,
the text area defaults to the first value and changing the
combo box item and pressing calculate doesn't change the
value of the text box.
Any help would be appreciated, thanks

//On calculate_btn release
//Math functions

//If combo box = data no. then change label
if (class_cb.selectedItem.data = 1) {
shaft_ta.text = "6";
} else {
if (class_cb.target.selectedItem.data = 2){
shaft_ta.text = "7";
} else {
