FormViewModeEventHandler Delegate

 

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

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

type FormViewModeEventHandler = 
    delegate of 
        sender:Object *
        e:FormViewModeEventArgs -> unit

Parameters

sender
Type: System.Object

The source of the event.

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

A FormViewModeEventArgs that contains the event data.

The ModeChanging event is raised when a FormView control attempts to switch between edit, insert, and read-only mode, but before the mode actually changes. This allows you to provide an event-handling method that performs a custom routine, such as configuring the FormView control for a specific mode or canceling the mode change, whenever this event occurs.

When you create a FormViewModeEventHandler 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 NIB: Events and Delegates.

The following example demonstrates how to programmatically add a FormViewModeEventHandler delegate to the ModeChanging event of a FormView control.

System_CAPS_security Security Note

The control in this example has a text box that accepts user input, which is a potential security threat. By default, ASP.NET Web pages validate that user input does not include script or HTML elements. For more information, see Script Exploits Overview.
