Comments on: Silverlight AutoCompleteBox: What’s new in the December release http://www.jeff.wilcox.name/2008/12/december-autocompletebox/ Silverlight, rich client apps and web development Mon, 06 Feb 2012 19:09:00 +0000 hourly 1 http://wordpress.org/?v=3.3.1 By: Pete http://www.jeff.wilcox.name/2008/12/december-autocompletebox/comment-page-1/#comment-1042 Pete Sat, 13 Dec 2008 14:25:38 +0000 http://www.jeff.wilcox.name/2008/12/11/december-autocompletebox/#comment-1042 Thanks Jeff and wackyphill for your advice and suggestions, which I will certainly look into. I accept and understand the point about added complexity, however I would have thought the majority would be happy with the tradeoff. Having said that, I have nothing to back myself up, so bow to your greater experience. Thanks Jeff and wackyphill for your advice and suggestions, which I will certainly look into.

Typical auto complete implementations out there are designed to be extensible; leaving it up to developers to implement any special validation logic in their application-level code. Is there not a way for you to perform your own validation when the control loses focus (such as checking for a null SelectedItem, and clearing Text in that case)? From my perspective, if I exposed a property that restricted input to just the items - then I would also have to expose a validation model, events, value coercion, and a bunch of other things that could raise the complexity of the control. @Pete,

IMHO this control is fine for one or two scenarios. However, to be really useful, it needs to be able to restrict choices to items that appear in the box. Without that facility, it is not much more than a toy. IMHO of course! Pete Hello Jeff,
