PropertyPath Class

Implements a data structure for describing a property as a path below another property, or below an owning type. Property paths are used in data binding to objects, and in storyboards and timelines for animations.

XAML Values

propertyPath

A string that is evaluated to be either a simple or complex property path. The syntax for setting a PropertyPath in XAML is versatile but complex, and is described in the separate topic PropertyPath XAML Syntax.

This class contains a string Path, and list of dependency properties that are the PathParameters into the string Path.

PropertyPath supports two modes of behavior:

Source mode describes a path to a property that is used as a source for some other operation. This mode is used by the Binding class to support data binding.

Target mode describes a path to a property that will be set as a target property. This mode is used by animation in support of storyboard and timeline setters.

For instance, Background.Opacity is a two-step path. This path implies: first, find the Background property of an object, get the value object that the Background property is set to, and then get the value of the Opacity property on that object.
