Exposing properties from the custom control

Most of the time, while using custom controls, we need to expose additional properties based on the requirement. In this recipe, we will demonstrate exposing dependency properties from the custom control and binding the record to the UI.

Getting ready

Let's extend our previous project to perform these steps. To get started, launch Visual Studio and open the project CH05.SearchControlDemo.
