GridView::OnRowDeleting Method (GridViewDeleteEventArgs^)

.NET Framework (current version)

Raises the RowDeleting event.

Namespace: System.Web.UI.WebControls
Assembly: System.Web (in System.Web.dll)

Syntax

protected:
virtual void OnRowDeleting(
	GridViewDeleteEventArgs^ e
)

Parameters

e: Type: System.Web.UI.WebControls::GridViewDeleteEventArgs^
A GridViewDeleteEventArgs that contains event data.

Exceptions

Exception	Condition
HttpException	There is no handler for the RowDeleting event.

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

Raising an event invokes the event handler through a delegate. For more information, see NIB: Raising an Event.

The OnRowDeleting method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

Notes to Inheritors:

When overriding OnRowDeleting in a derived class, be sure to call the base class's OnRowDeleting method so that registered delegates receive the event.
