I do some validating in the ColumnChanging event handler of my datasource. If there is an error, I throw an exception. The grouping grid reacts to this by painting the column with a red error icon. However, it does not show the exception message in a message box. Is there a way I can the grid to display a message box also? I can of course display a message box myself in the ColumnChanging handler, but since the same datasource will also be edited by other viewers that do display a message box, this might lead to two identical messages boxes.

I think you will have to have to listen to the ColumnsChanged event, and if there is a new RowError set, display the message. Here is a try at this using a hashtable to tack the errors on each row. http://www.syncfusion.com/Support/user/uploads/GGC_ColumnError_af89350.zip
