How to: Bind to an Enumeration

This example shows how to bind to an enumeration by binding to the enumeration's GetValues method.

In the following example, the ListBox displays the list of HorizontalAlignment enumeration values through data binding. The ListBox and the Button are bound such that you can change the HorizontalAlignment property value of the Button by selecting a value in the ListBox.
