Hi all,

I have an issue with an AJAX.NET enabled web site that i have written. This site was completed and worked fine on our dev server, but then the dev server was rebuilt, and then the fun began. I have reloaded the site onto the newly setup server, installed AJAX.NET (the current version, which i also developed the site under). But the site will not load and i keep getting the follow error

Parser Error Message: Could not load type 'System.Web.UI.Compatibility.CompareValidator' from assembly 'System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'.

Source Error:

I have tried uninstalling and reinstalling AJAX.NET, Moving the 2 AJAX dll's into the projects BIN directory, and also manually putting the 2 AJAX dlls into the GAC, and nothing has made a bit of difference, and so im posting on here.......

any help would be greatly appreciated!

Here is a pointer to a blog post that describes how you can download the compatibility validators: http://weblogs.asp.net/scottgu/archive/2007/01/25/links-to-asp-net-ajax-1-0-resources-and-answers-to-some-common-questions.aspx

Hope this helps,

I am working on a team project.

On Other system they haven't got this error.

On my system I have commented the following lines in the web.config {locally}

Then I can't get this error.{I don't know why this error appear on my system and doesn't on other systems}

If i comment these line in my project which all team developer work what could be the result ?

What Should I do ?

So I uninstalled the latest ajax extension and install the old one.

Then as on other system enable the lines above then my application start working on my system.

Now What Should I do .Can I install the new extension on all systems and comments these lines on other system as well.

{I am asking it as Could it lead to some problems or not}
