I capture the KeyUp event on an AutoComplete box from the Silverlight toolkit. If they press Escape I want to clear the value by calling autocompletebox.Text = string.Empty. This works most of the time, but whenever I set this when the whole field is selected it does not work. Is there another property that I should be setting instead of Text?
Try also assigning null to the SelectedItem
property.
BTW Why are you using the toolkit, Silverlight 4 has an AutoCompleteBox, are you using SL3?
