AutoCompleteBox Dropdown width

Question

Can the width of the dropdown be set to a different value than the AutoCompleteBox itself?

Answer 1

The Popup is a separate Part of the AutoCompleteBox, so it should be possible to extend that beyond the width of the text box.

In Blend, right-click on the AutoCompleteBox and select Edit Template > Edit a Copy, giving the new template a name.

Drill-down in the Objects and Timeline window to the 'Popup' part, and beneath that is a Grid. Change the width of that Grid to change the width of the popup content whilst maintaining the current width of the text box).

(I must admit I've only had chance to do this in Silverlight Spy, but it definitely works there so I can't see it being a problem doing it through Blend).
