The best control from the AJAX Control Toolkit - Validator Callout Extender

Published to Blog on 22 Dec 2006

I have used a couple of controls from the ASP.NET AJAX Control Toolkit, namely the Animation Extender and the Drop Shadow for the AJAX Showcase. But today I spent some time with the new Validator Callout Extender. I have to tell you that I believe that this is currently the most useful, user-friendly, and easiest to implement control in the toolkit.

Simply awesome.

    This control may work great if the default settings are to your liking, but it's a PITA otherwise. I'm not having any luck changing the css. The documentation is lacking big time.

    The ajax control toolkit 3.5 actually allows changes to be made with predefined css classes. I believe anything early requres changes to be made in the code. I have written a few specifics about it on <a href=" title="Change Validator Callout Extender Colors">my blog</a>, and you can see how I used css to change the styling on a form I designed <a href="" title=" books Validators">here</a>. I agree that the Callout Extender is one of the most usefull controls and I really wish there was a control similar to it for developing Windows client applications.
