DetailsViewUpdateEventHandler Delegate

Represents the method that handles the ItemUpdating event of a DetailsView control.

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

public delegate void DetailsViewUpdateEventHandler (
	Object^ sender, 
	DetailsViewUpdateEventArgs^ e
)
/** @delegate */
public delegate void DetailsViewUpdateEventHandler (
	Object sender, 
	DetailsViewUpdateEventArgs e
)
Not applicable.

Parameters

sender

The source of the event.

e

A DetailsViewUpdateEventArgs that contains the event data.

The DetailsView control raises the ItemUpdating event when an Update button (a button with its CommandName property set to "Update") within the control is clicked, but before the DetailsView control updates the record. This allows you to provide an event handler that performs a custom routine, such as HTML-encoding the values of a record before updating it in the data source, whenever this event occurs.

When you create a DetailsViewUpdateEventHandler 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.
