ModelProperty Class

[This documentation is for preview only, and is subject to change in later releases. Blank topics are included as placeholders.]

A ModelProperty represents a property on a ModelItem. Model properties are associated with an instance of an item, which allows them to have simple Value get/set properties instead of using the more cumbersome GetValue/SetValue mechanism of PropertyDescriptor.

Namespace:  System.Activities.Design.Model
Assembly:  System.Activities.Design.Base (in System.Activities.Design.Base.dll)

The value of a ModelProperty may come from a locally set value, or it may be inherited from somewhere higher up in the element hierarchy. Use the Source property of the value returned by Value to determine the source of the property value.
