ViewEventHandler Delegate

Represents the method that will handle the ViewEvent event that is raised by visual design tools, such as Visual Studio 2005, implementing the IControlDesignerView interface. This class cannot be inherited.

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

public delegate void ViewEventHandler(
	Object sender,
	ViewEventArgs e
)

Parameters

sender
Type: System.Object

The source of the event.

e
Type: System.Web.UI.Design.ViewEventArgs

A ViewEventArgs object that contains the event data.

When you create a ViewEventHandler 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.

The ViewEvent event is raised by the designer host for certain actions on a control on the design surface. The ViewEvent event is handled by a ViewEventHandler delegate method, which takes a ViewEventArgs object as a parameter.

Typically, control designer classes do not directly implement or assign a ViewEventHandler delegate. The ControlDesigner base class supplies a default delegate for the ViewEvent event. Custom control designers override the OnClick, OnPaint, and OnTemplateModeChanged methods to process those events for the control on the design surface. The Initialize method sets the default event delegate for the ViewEvent delegate.
