The DetailsView control raises the ItemDeleting event when a Delete button (a button with its CommandName property set to "Delete") within the control is clicked, but before the DetailsView control deletes the record. This allows you to provide an event handler that performs a custom routine, such as verifying a record before deleting it, whenever this event occurs.

A DetailsViewDeletedEventArgs object is passed to the event handler, which allows you to determine the index of the record being deleted and to indicate that the delete operation should be canceled. To determine the index of a record, use the RowIndex property. To cancel the delete operation, set the Cancel property to true. You can also access the key fields and non-key fields by using the Keys and Values properties, respectively. These values are useful if you want to verify the record before deleting it.


It is possible to modify the key field values in the Keys property. If you change these values, the record that corresponds to the new key field values will be deleted.

For more information about handling events, see NIB: Consuming Events.

The following code example demonstrates how to use the DetailsViewDeleteEventArgs object passed to the event handler for the ItemDeleting event to cancel a delete operation.
