ContextItem.OnItemChanged Method

Represents a method that is called on the context item before it is stored in the context item manager. The previous item in the context item manager is passed as a parameter.

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

protected virtual void OnItemChanged(
	EditingContext context,
	ContextItem previousItem
)

Parameters

context
Type: System.Activities.Presentation.EditingContext
The EditingContext within which the change is being made.
previousItem
Type: System.Activities.Presentation.ContextItem
The previously active ContextItem.

Because items must have default constructors, a default item will be constructed if an item is passed into the context the first time.
