Custom Classes with Dependency Properties Sample

This sample shows how to create and register dependency properties for use in the same application, instead of defining dependency properties as part of a separate assembly. This example illustrates the following scenarios:

• A class registers a dependency property for its own use.
• A class implements several callbacks, such as CoerceValueCallback, PropertyChangedCallback, and ValidateValueCallback, for a set of related dependency properties. The callbacks are also used to adjust the values of other properties or to prevent an initial invalid value set. These callbacks are registered as part of the dependency property characteristics of a dependency property. Whenever the appropriate condition is detected by the property system, the user-defined callback is invoked. For instance, a change in the effective value of a property invokes the registered PropertyChangedCallback .
