Had the same issue, adding the following lines to top of .asx/.aspx file fixed it:
assembly="System.Web.Extensions, Version=188.8.131.52, Culture=neutral, PublicKeyToken=31BF3856AD364E35"
assembly="System.Web.Extensions, Version=184.108.40.206, Culture=neutral, PublicKeyToken=31BF3856AD364E35" %>
Items don't appear in toolbox yet, but design view works...

For the AJAX Control Toolkit, you need to add it to your Toolbox manually.

This message did help me to have <asp:ListView> put into action in VS2008, I was missing the controls assembly System.Web.Extensions

I am also getting the same error. Unknown server tag <asp:listview>.
I added these lines in my web.config file
also I reinstalled .net framework SP1 twice but all in vain. Still the problem persist.
Please help to solve out this problem.

I did as you said and added the tags in web.config and it worked. My website
