FormViewDeleteEventHandler Delegate

Represents the method that handles the ItemDeleting event of a FormView control.

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

type FormViewDeleteEventHandler = 
    delegate of  
        sender:Object * 
        e:FormViewDeleteEventArgs -> unit

Parameters

sender
Type: System.Object

The source of the event.

e
Type: System.Web.UI.WebControls.FormViewDeleteEventArgs

A FormViewDeleteEventArgs that contains the event data.

The FormView control raises the ItemDeleting event when a Delete button (a button with its CommandName property set to "Delete") within the control is clicked, but before the FormView control deletes the record. This allows you to provide an event-handling method that performs a custom routine, such as verifying a record before deleting it, whenever this event occurs.

When you create a FormViewDeleteEventHandler 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.
