GridView.RowDeleted Event

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

Namespace:  System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)
'Declaration
Public Event RowDeleted As GridViewDeletedEventHandler
<asp:GridView OnRowDeleted="GridViewDeletedEventHandler" />

The RowDeleted event is raised when a row's Delete button is clicked, but after the GridView control deletes the row. This enables you to provide an event-handling method that performs a custom routine, such as checking the results of the delete operation, whenever this event occurs.

A GridViewDeletedEventArgs object is passed to the event-handling method, which enables you to determine the number of rows affected and any exceptions that might have occurred. You can also indicate whether the exception was handled in the event-handling method by setting the ExceptionHandled property of the GridViewDeletedEventArgs object.

For more information about handling events, see Consuming Events.

The following example demonstrates how to use the RowDeleted event to check the result of the delete operation. A message is displayed to indicate to the user whether the operation succeeded.

    ' Display whether the delete operation succeeded.
    If e.Exception Is Nothing Then

      Message.Text = "Row deleted successfully."

    Else

      Message.Text = "An error occurred while attempting to delete the row."
      e.ExceptionHandled = True

    End If

  End Sub
