I want to trap the event when the users clicks on the plus signs to expand the child data - what event is this ? I am new to infragistics...

 I tried this, but can't handle any events that relate to band - this is for a sort - not quite what I need.

Private Sub UltraGrid1_Change(ByVal sender As Object, ByVal e As Infragistics.Win.UltraWinGrid.BandEventArgs) Handles UltraGrid1.AfterSortChange

thanks
