Have you tried to re-install the AJAX library again?

of course I tried to re-install AJAX but nothing happened

Sorry that I asked, but sometimes those are the common errors. Also are you sure that you installed 1.0 instead of 3.5?

As I saw in the version tab it is 1.0.does it cause trouble to install version 3.5 instead of 1.0?(if my problem is solved in this case)

hello.

well, the validators are not on the system.web.extensions assembly. I think that they're on the validators dll:

btw, if you update your app to use the new version, i think that you no longer need to use those validators.

Developing forums using Atlas

Hello,
I was interested in adding a 'dynamic' forum to my site (something somewhat similar to these forums) - I am currently developing in .NET as well as using some components of Atlas

Was curious as to whehter there is a project anyone is working on, or if there is free code available to tinker with

(I searched around but have not found anything worthwile)

Thanks in advance

I have not done ity et, but I think a forum is a great place to add that kind of functionality. If you're already working on the site, then I'd probably think about starting with wrapping some of your existing controls with updatepanels and / or the collapsible panel that the toolkit has.
