Hi svibuk,<!--?xml:namespace prefix = "o" ns = "urn:schemas-microsoft-com:office:office" /--><o:p></o:p>
cannot use toolscriptmanager as using framework 2.0

For this issue, I suppose the reason is that you doesn't add the AjaxControlToolkit.dll as a reference to your application. I suggest you download the AJAX Control Toolkit
from this site. And reinstall the Ajax control Toolkit.
You could refer to the following link.

If you have any other questions about my reply, please let me know freely.
