Error with Update Panel in asp.net

Hi,

be sure to modify the web.config file with the settings needed for supporting ASP.NET AJAX.

For example, you need to add an entry for the ScriptResource HTTP handler:

<system.web>
 <httpHandlers>
 <add verb="GET" path="ScriptResource.axd"
 type="Microsoft.Web.Handlers.ScriptResourceHandler"
 validate="false"/>
 </httpHandlers>
</system.web>

My suggestion is to copy the settings from the web.config file installed in the template websites by the ASP.NET AJAX Extensions installer.

Yes please make sure that web.config has all the enteries specified by AJAX to make it run properly

Which version of Ajax u r using?

Have u created your site using "AjaxEnabledSite" like

File->New Website->My Templates->AjaxEnabledSite

So that all requred parameter for web.config will be imported...

Try it..
