Using the Ultra Grid designer or in code you have to set the override expansion indicator property of the band in question:

Band.Override.ExpansionIndicator = ShowExpansionIndicator.CheckOnDisplay

Perfect, thanks

Note that in order to determine whether a parent row has child rows, the grid has to ask the BindingManager to retrieve the child rows collection. This could cause some performance issues, depending on the data source (which is why the grid does not do this by default).
