EditingScope Class

Definition

An editing scope represents a collection of changes to the ModelItem tree that can be committed or rolled back as one atomic unit of work.

public ref class EditingScope : System::Activities::Presentation::Model::ModelEditingScope
public class EditingScope : System.Activities.Presentation.Model.ModelEditingScope
type EditingScope = class
    inherit ModelEditingScope
Public Class EditingScope
Inherits ModelEditingScope
Inheritance
EditingScope

Remarks

This is useful for batching together a set of changes to multiple ModelItem objects. As an example, in the messaging activities, the changes made from the raised dialogs will impact multiple property values. However, as all of the changes come from the raised dialog, the changes need to be considered as a batch and undone as a single unit of work. For more details on usage, see the Editing Scope sample
