This example demonstrates how to achieve AutoCompleteTextBox in WPF Application.

To assist with data entry, Microsoft Internet Explorer 5 and later and some other browsers support a feature referred to as AutoComplete. AutoComplete monitors aTextBox and creates a list of values entered by the user. When the user returns to the text at a later time, the list is displayed. Instead of retyping a previously entered value, the user can simply select the value from this list.

In this example, we'll create a TextBox that automatically completes input strings by comparing the prefix being entered to the prefixed of all strings in a maintained source. This is useful forTextBox controls in which URLs, addresses, file names, or commands will be frequently entered.
