Hi Mathi,

If you're asking about the lack of red border when using DropDownByIndex, I asked exactly the same question:

Since I didn't get an answer, I opened OSS. As soon as I get an answer I will post it here...

Hi Mathi,

First time when the page loads,show a blank value in the drop down as default (for blank index = -1). Now when the user changes this value, leadselection will be changed. Display the message(to select an entry from drop down) if the lead selection <0.

To set the value as blank by default: set the selection cardinality to 0:1

What do you mean with "mandatory"? Do you mean that a value must be selected before some action may be executed? If yes, just check in the action handler that there is a value selected, i.e. there is a lead selection in the node that provides the dropdown list values:

void onListEntrySelected(...)
{
  if ( wdContext.node<Values>().getLeadSelection() != IWDNode.NO_SELECTION)
  {
    /* process action */
  }
  else
  {
    /* show message */
  }
}
