TreeGrid.addRecordClickHandler() make sure to call super.onRecordClick(event) though as well.

this recordClickHander() is called when a node is clicked..
its is not called when a checkbox corresponding to a node is clicked..
i want the event on click of checkbox.
have used selectionAppearence for the checkbox!

Well the record includes the checkbox you just have to do more work, the only other way is to addSelectionChangedHandler()

In TreeGrid or ListGrid there is no addSelectionChangedHandler()..!
now?

So this is the last reply I'll give but literally take this example
http://www.smartclient.com/smartgwt/showcase/#tree_checkbox
and add this code to it

employeeTreeGrid.addSelectionChangedHandler(new SelectionChangedHandler() {
  @Override
  public void onSelectionChanged(SelectionEvent event) {
    SC.say("I clicked the checkbox");
  }
});

if it doesn't work it is an issue on your own end and you need to figure it out.

I think you can use

public void onDataArrived(DataArrivedEvent event)
{
	setSelectedState(" .... ");
}
