Does anyone know about a WPF conponent that acts like the gmail to field?

Where the To-field is a textbox that also contains a dropdown, where each new contact is added to the text field? Similar to the facebook to field, where a box is created for each receiver.

Is there such a library or compon开发者_开发百科ent out there?

Thanks
