title: AutoComplete-ready ComboBox in Silverlight 3
body: <p>Has anybody out there had a situation where you needed to implement an "editable" ComboBox in Silverlight?  My client wants a ComboBox in their UI that allows the user to place focus on the selection box and start typing to automatically pull up the desired value from the available items, rather than requiring use of the drop-down list.</p>
  
  <p>This feature is available, I know, in several implementations from third parties.  For example, you can make this happen fairly easily with Telerik's RadControls for Silverlight.  However, my client is restricted to using the Silverlight 3 Toolkit, with no third-party tools or plug-ins.</p>
  
  <p>Any suggestions for a quick, down-and-dirty implementation?  Any guidance or links are appreciated!</p>
  
  <p>Thanks,
  Jeff</p>
