Intellisense for WPF application

Question

Hi,

I've been searching for a control that gives me the ability to add intellisense to my textbox.
If the user is typing pat. I would like to create an intellisense out of an existing collection to select the name of that object.
So I' m not searching for an autocomplete texbox but something like in the editor of visual studio, when i'm writing text in a C sharp file.

Does anyone know a control that can do that?

Greetings
