EditingContext Class

Article
11/17/2011

The EditingContext class contains contextual state about a designer. This includes permanent state such as list of services running in the designer. It also includes transient state consisting of context items. Examples of transient context item state include the set of currently selected objects as well as the editing tool being used to manipulate objects on the design surface. The editing context is designed to be a concrete class for ease of use. It does have a protected API that can be used to replace its implementation.

The default implementation creates a ServiceCollection that supports delayed activation of design editor managers through the declaration of a SubscribeService attribute on the design editor manager.
	Dispose() () () ()	Disposes this editing context.
	Dispose(Boolean)	Disposes this editing context. <param name="disposing">True if this object is being disposed, or false if it is finalizing.</param>
	Equals	(Inherited from Object.)
	Finalize	Finalizer that implements the IDisposable pattern. (Overrides Object..::..Finalize() () () ().)
