Hi Pankaj,

You can do this dynamically n set the initial value to any of the value,

use the following code:-

Say you have an attribute 'drop_by_key' mapped to the dropdown by key UI element. Then you can set the first key as selected as

String attributeName = IPrivateMyTestView.IContextElement.DROP__BY__KEY;

IWDAttributeInfo attributeInfo = wdThis.wdGetContext().getNodeInfo().getAttribute(attributeName);

ISimpleType simpleType = attributeInfo.getSimpleType();

ISimpleValueSet valueset = simpleType.getSVServices().getValues();

valueset.putValues("<Insert values in value set>");

Object key = valueset.getKey(0);

wdContext.currentContextElement().setDrop_by_key((String)key);

this way you can assign any value in the getKey() function ..

Hope this helps

Jeet.

Hi

Before populating the values into dropdown set a value for context attribute.

wdContext.currentContextElement.setV_Name ("Select a value");

and then populate your list according to your requirement.

Hi Pankaj,

Set the key of the value you want to display, to the context variable of drop down.Then the corresponding value will be displayed

ie. If u r having key-Value pairs like

Key1-->Value1

Key2-->Value2

then, inorder to display Value2 at start,

assign Key2 to the context of dropdownByKey

ie. wdContext.currentContextElement().set<con.Var>(Key2);
