I have gone through a lot of AutoComplete TextBox in WPF articles. This article is a simple approach for achieving AutoComplete for TextBox.

Crating WPF Application Project

Fire up Visual Studio 2008 and Create a WPF Application and name the project as AutoCompleteWPF.

Create a sample data, in our case it is List of Strings.

Now in TextChanged event we need to write the below code:
