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.

The PropertyPath type exposes the following members.

  NameDescription
Public methodPropertyPath(Object)Initializes a new instance of the PropertyPath class.
Public methodPropertyPath(String, array<Object>)Initializes a new instance of the PropertyPath class, with the provided pathing token string and parameters.

  NameDescription
Public propertyPathGets or sets the string that describes the path.
Public propertyPathParametersGets the list of parameters to use when the path refers to indexed parameters.

  NameDescription
Public methodEquals(Object)Determines whether the specified object is equal to the current object. (Inherited from Object.)
Public methodGetHashCodeServes as the default hash function. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

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.
