I have nested tables bound to a hierarchical dataset. I register QueryCellInfo event handlers on the child table during the RecordExpanded event of the parent row. How do I remove these QueryCellInfo event handlers later on when the parent rows are deleted? I tried handling the GridDataTable.RecordDeleting event but that never fires?

Thanks.

Hi Kiran,

Thanks for your update.

RecordDeleting event of the GridDataTable will be raised whenever you delete the record by pressing "Delete" key. But, It will not be raised when you delete the record in the underlying collection in the code behind.

RecordDeleting event of the dataGrid.Model is working fine. For your reference, Please find the sample in the below location,
