EditingContext Class

Contains contextual state information for a designer, such as the WorkflowDesigner. This includes permanent state information, such as the list of services running in the designer. It also includes transient state consisting of context items including the set of currently selected objects as well as the editing tool being used to manipulate objects on the design surface.


Namespace:  System.Activities.Presentation
Assembly:  System.Activities.Presentation (in System.Activities.Presentation.dll)

public class EditingContext : IDisposable

The EditingContext type exposes the following members.

Public methodEditingContextInitializes a new instance of the EditingContext class.

Public propertyItemsReturns the local collection of context items stored by the current editing context.
Public propertyServicesReturns the service manager used in the current editing context.

Protected methodCreateContextItemManagerCreates an instance of the context item manager that is returned by the Items property.
Protected methodCreateServiceManagerCreates an instance of the service manager to be returned from the Services property.
Public methodDispose()Immediately releases any unmanaged resources used by the object.
Protected methodDispose(Boolean)Immediately releases the unmanaged resources used by the current EditingContext object.
Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

Public eventDisposingOccurs when the Dispose method is called or when the EditingContext object is finalized and collected by the garbage collector of the Microsoft .NET common language runtime.

The EditingContext represents the communication boundary that is shared between the hosting application and the Windows Workflow Designer. The EditingContext was implemented as a concrete class for ease of use. Override CreateServiceManager() and CreateContextItemManager() to use customized managers derived from ServiceManager and ContextItemManager.
