Occurs when a row's Delete button is clicked, but before the GridView control deletes the row.

The RowDeleting event is raised when a row's Delete button is clicked, but before the GridView control deletes the row. This allows you to provide an event-handling method that performs a custom routine, such as canceling the delete operation, whenever this event occurs.
A GridViewDeleteEventArgs object is passed to the event-handling method, which allows you to determine the index of the current row and to indicate that the delete operation should be canceled. To cancel the delete operation, set the Cancel property of the GridViewDeleteEventArgs object to true. You can also manipulate the Keys and Values collections, if necessary, before the values are passed to the data source.
For more information about handling events, see Consuming Events.
The following code example demonstrates how to use the RowDeleting event to cancel the deleting operation if the user attempts to remove the last record from a GridView control.
