PropertyPath Class

Remarks

For XAML usages of a PropertyPath, as well as related property-path concepts, see Property Path Syntax.

In WPF, a property path could be constructed using different constructors depending on its intended usage (data binding or timelines). In Silverlight 5, you typically construct a PropertyPath based on a string, regardless of intended usage. You can also construct a PropertyPath with a DependencyProperty identifier reference, if all you need is a property reference for a PropertyPath-type property in code and you are not requesting a true path. See Property Path Syntax for a guide to constructing a PropertyPath based on a string, with separate syntax guidance for each usage.
