Deploying RadControls into MOSS 2007 WebParts

[John]

Hi All,
I'm working on a project where deployment of RadControls into SharePoint 2007 WebParts is essential.  I've followed the steps on the documentation site (http://www.telerik.com/help/aspnet-ajax/moss-deploying-radcontrols.html), but I am getting the following permissions error when I load my user control webpart into a web part zone: 

CreateChildControls_Exception: "Access to the path 'C:\Inetpub\wwwroot\wss\VirtualDirectories\80\UserControls\myTreeControl.ascx' is denied."

I'm not sure if additional configuration apart from what is included in the documentation is neccessary.  Please help if you can.

Thanks,
John P.

I've fixed the previous problem, but now when the web part loads, there is no ajax functionality.  Every event fires a full page refresh.  Any ideas why this is happening?

Here is my code.  When I run the web part on SharePoint everything works except the ajax post back functionality and I get the following error message displaying below the control: 

CreateChildControls_Exception: The control with ID 'UpdatePanel1' requires a ScriptManager on the page. The ScriptManager must appear before any controls that need it.

This would lead me to believe that for some reason my ScriptManager is not doing its job.  Any suggestions?

Hello John ,

Can you please try to add the ScriptManager to the page's Form controls collection instead of the webpart's controls collection. Similar to this:

this.Page.Form.Controls.Add(scriptHandler);

If you continue to experience difficulties please sent us (attached to a formal ticket) a working project in which this behavior can be observed. Thus we will do our best to provide more to-the-point answer/solution.

Best regards,

Rosen,
Thanks for the help.  That actually fixed the problem.  I was also having issues adding two ajax enabled web parts to the same page, but that has been fixed as well.  Thanks again.
