AJAX Tool kit Combox
AJAX Tool kit Combox
This is a sample of using AjaxToolkit Combox. I don't want to say it is good or not. We are just meet each other today and I feel like it very much.
Here is the screen shot for this example.
The first step is to add a combox to the page. Then configure its style and set its porperties. Don't forget to add scriptManager to your page. Ok, here is the style and the configured items. It's also available in the source code of ajaxtoolkit sample site.
