I’m interested in using an AJAX extension, namely this textbox calendar control.
Has anyone else ever had a hard time getting any AJAX controls to show up?

Surely all the excitement about AJAX isn’t from the six controls listed above.
Would this be a corrupt install?
I’ve changed my Project’s Target framework down from .NET Framework 4 to .NET Framework 3.5, closed VS2010 and reopened it. Still the same.
I also tried a Right-Click and selected Reset Toolbox, but that did nothing either.
What’s going on? Am I the only one having this problem?
You need to download the ASP.Net AJAX Control Toolkit.
They aren’t built-in.
