Ajax Issues - Update Panel / Timer. Intellisense doesn't know about them

Posted on 16th Feb 2014 by admin

Type 'System.Web.UI.ScriptManager' does not have a public property named 'UpdatePanel'. That is what I get when I created a new Ajax website with Visual Web Developer 2008. All other sites on this server were developed with VWD 2005, but I wanted to update everything to version 3.5. I created a new site from scratch, created new webpages (copying in the appropriate HTML) and added the controls (scriptmanager, updatepanel, timer, contenttemplate) manually. Of those 3, intellisense only seems to understand what scriptmanager is :( So - the website will not work. I tried to search the forums and the web to find out why this might happen but keep coming up with nothing. Can someone help? This should be simple, according to all the hype :) Thank you!
