#1,009 – ComboBox Data Binding Basics, Part I
February 14, 2014 2 Comments
As with a ListBox, you can use data binding to load and manage the items displayed in a ComboBox control.
You set the ItemsSource property of the ComboBox to a collection that implements the IEnumerable interface. The collection bound to can contain any type of object.
If you want the ComboBox to display simple strings, you can set the DisplayMemberPath property to the string-typed property of a bound object that should be used to get the display string for each item.
<ComboBox ItemsSource="{Binding ActorList}" Margin="20"
DisplayMemberPath="FullName"/>
