ScreenCast: How to create and use an ASP.NET AJAX Control Extender

In this 13 minute video I walk through creating and deploying an example ASP.NET AJAX Control Extender.

The example extender automatically disables buttons when they are clicked, to stop people clicking them twice (for example on a purchase form).  Implementing this isn’t as obvious as you might think, and involves cloning.

Screenshot from the video

I do absolutely everything from scratch including writing the server-side and browser-side code, and creating a web site to test the extender.

The video can be viewed/downloaded here.

Please make sure you have sound playing since I talk through a lot of what I am doing.

    Hello Pedro,

    I’ve just checked at they work for me … can you try again? Is it possible you are behind a firewall that is blocking access? Perhaps right-click on the link and save the WMV file to disk…
