I have a grid that's bound to a BindingSource<MyApplicationsBusinessObjects>, and I see the Infragistics data validation messageboxes, such as "Unable to update the data value: object of type X cannot be converted to type Y".
I'd like to implement my own messageboxes and data validation. How do I do this?
Try trapping the Error or CellDataError event of the grid. The event arguments have a property that controls whether or not to display the default message. So you can cancel the message and display your own.
