Hi Kishore,

Rather than using code for this, use the properties of the node.

Set the cardinality to 1...n (This will remove the initial blank from the list) and set Initialize lead selection to True (this will set the lead selection to the first element).

hi,

1.in ur context create a context value node----eg: MyStates

2.under that value node create a value attribute--eg: values.

3.set the cardinality of "MyStates" value node to 0:n

4.texts property of ur dropdown by index ui element shld be bound to the value attr (values).

5.in the wdDoInit() method of ur view that has this dropdownbyindex ui element use the follwoing code,

String    [  ]    states_array    =        new String [  ]   {"tn", "mp", "ap", "karnataka"};
List list_for_node_elem = new ArrayList();

   for (int i =  0; i <states_array.length; ++i)

   {

      IPrivateMyView.IMyStatesElement elem = wdContext.createMyStatesElement();
      MyStatesElement.setValues(states_array   [i ]   );
      list_for_node_elem.add(MyStatesElement);

   }

   wdContext.nodeMyStates().bind(list_fornode_elem);

   wdContext.nodeMyStates().setLeadSelection(1);

Hi,

just add the "Select State" string to array object "states_array"

String [ ] states_array = new String [ ] {"Select State","tn", "mp", "ap", "karnataka"};

// remaining code from the Jayapriya post

wdContext.nodeMyStates().setLeadSelection(0);

Hi,

Please go through this link

http://help.sap.com/saphelp_nw70/helpdata/EN/4a/8613e41629344194e4f40393740d51/frameset.htm

if you are using the rfc to populate the DropDownByIndex then just bind the output attribute to texts property of the dropdown and execute the rfc in DoInit method of the view.
