GridViewUpdateEventHandler Delegate

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

Represents the method that handles the RowUpdating event of a GridView control.

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

public delegate void GridViewUpdateEventHandler (
	Object^ sender, 
	GridViewUpdateEventArgs^ e
)
/** @delegate */
public delegate void GridViewUpdateEventHandler (
	Object sender, 
	GridViewUpdateEventArgs e
)
JScript supports the use of delegates, but not the declaration of new ones.

Parameters

sender

The source of the event.

e

A GridViewUpdateEventArgs object that contains the event data.

The RowUpdating event is raised when a row's Update button is clicked, but before the GridView control updates the row. This allows you to provide an event-handling method that performs a custom routine, such as canceling the update operation, whenever this event occurs.

When you create a GridViewUpdateEventHandler delegate, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate. For more information about event-handler delegates, see Events and Delegates.
