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.

Public NotInheritable Class PropertyPath

Inheritance: Object
PropertyPath

Attributes: TypeConverterAttribute

Remarks

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.

XAML Attribute Usage
