Unbound checkbox column, GGC and bindingsource

Hi

I am trying to add an unbound checkbox column to a grid grouping control by using the code in the knowledge base (http://www.syncfusion.com/support/kb/grid/Default.aspx?ToDo=view&questId=293). However, the code in the save event returns -1 as the recordindex if the datasource of the GGC is a bindingsource. If I use a datatable, it works. Unfortunately, I must use a bindingsource. Could you please provide a solution?

Regards,
Johan
