sujesh,

1. If your Table has no property compatabilityMode (check on UI designer in IDE), then every event occurs on lead selected element, you may get its index in action event handler like:

wdContext.node<NameOfNodeThatIsTableDataSource>().getLeadSelection();

2. Otherwise add parameter "row" of Java type IWDNodeElement to action, then add following to wdDoModifyView:

if (firstTime) {
  final IWDButton btn = (IWDButton)view.getElement("id-of-button");
  btn.mappingOfOnAction().addSourceMapping("nodeElement", "row");
}

Then in action event handler you may just use row.index();

Hi ,

Try this,

Create a node element in the node.And bind the number of row to the element.At runtime you can get the number by retriving the lead selection method.

int num=wdContext.current<Tablenode>Element().get<NUmberParam>();

Kind Regards
