Autocomplete textbox in Windows Phone 7

I'm creating my 开发者_如何学Cfirst Windows Phone 7 application, and I'm struggling to find an autocomplete textbox. Is there an easy way to add one to the toolbox? Or do I need to create my own control?

The one from Silverlight 3's SDK, the AutoCompleteBox, works relatively well on the phone. It requires minimal styling changes to work.

There is a known issue today where selecting an item that pops up requires two taps: one to select and another to "really" select. We should have that issue in the platform (the bug is not in AutoCompleteBox) fixed by the time the phone development experience is ready.

AutoCompleteBox is in the Silverlight Tookit so you have to add a reference to that in your project.

After investigating it appears that there's not an auto-complete textbox control for windows phone 7 applications, so I've had to create one myself...
