RowDeleted Event

GridView.RowDeleted Event

Note: This event is new in the .NET Framework version 2.0.

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)

public event GridViewDeletedEventHandler RowDeleted
/** @event */
public void add_RowDeleted (GridViewDeletedEventHandler value)

/** @event */
public void remove_RowDeleted (GridViewDeletedEventHandler value)

JScript supports the use of events, but not the declaration of new ones.

The RowDeleted event is raised when a row's Delete button is clicked, but after the GridView control deletes the row. This allows 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 allows 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 code 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.


<%@ Page language="C#" %>

<script runat="server">

  void CustomersGridView_RowDeleted(Object sender, GridViewDeletedEventArgs e)
  {
    
    // Display whether the delete operation succeeded.
    if(e.Exception == null)
    {
      Message.Text = "Row deleted successfully.";
    }
    else
    {
      Message.Text = "An error occurred while attempting to delete the row.";
      e.ExceptionHandled = true;   
    }
    
  }
    
</script>
