Controlling Drop Down List

Hello Rene,

For example, if you have a context structure as follows:

Context

DDLBData (datasource node)

ValueHelpDDLB (context attribute mapped to DDL)

then you can default a value immediately after the population of the DDL as follows:

wdContext.nodeDDLBData().currentDDLBDataElement().setValueHelpDDLB(key);

About the second question, you do not have any automatic way to get the index of the selected item. But you can easily do it just by employing your own mechanism. Maybe, by maintaining a HashMap or some other mechanism. In Web Dynpro you have DropDownByIndex DDL but there is no such DDL in Adobe forms.

Hope that helps.

Thanks,

Hi ,

Is this is developed in webDynpro Adobe in Java ?

Are you using the following code to fill the Drop Down list box ?

Code in wdInit()

===========

IWDAttributeInfo attInfo =wdContext.nodeContext().getNodeInfo().getAttribute("Name");

ISimpleTypeModifiable attType = attInfo.getModifiableSimpleType();

IModifiableSimpleValueSet attValueSet =attType.getSVServices().getModifiableSimpleValueSet();

attValueSet.put("0","Value");

In Enter event of drop down list

========================

var jsToExecute = "event.target.SAPValueHelp(\"" + this.somExpression + "\");";

app.eval(jsToExecute);

For this when you select any value from drop down list box you can get the index of selection using the following code

int cnt

cnt =Integer.parseInt( wdContext .nodeContext().currentContext() .getName());

It gives you the index of the selection.

Please let me know if you need any info .

Hi

Thanks for your contributions. Setting the initial value of the DDL now works fine. Maybe my problem description was a little bit confusing. The DDL is part of an interactive form and its list data is provided by the underlying WD/Java. So what I need is to determine the index of the selection within the script of the change or exit event of the interactive form. This index should be used to retrieve further data fom another list in context data of the interactive form.

Any suggestion to resolve this requirement would be appreciated.
