Hi guys,
I found this excellent example
http://demos.telerik.com/aspnet-ajax/scheduler/examples/outlook2007/defaultcs.aspx
Which is just what I need to implement.
But when I copy and paste into my application I get this error
and stack trace
Do you have any clue, what I'm doing wrong?
Many thanks!

Hello Jan,
Did you wrapped the javascript code in a RadCodeBlock control as suggested in the stack trace and what is the result?

Hello Muhammad,
In order to fix the problem try moving the SPWebPartManager control in the MasterPage from the HEAD section into the BODY section of the html MasterPage.
This is what you need to move into the BODY:
<!--MS:<SharePoint:AjaxDelta id="DeltaSPWebPartManager" runat="server">-->
<!--MS:<WebPartPages:SPWebPartManager runat="server">-->
<!--ME:</WebPartPages:SPWebPartManager>-->
<!--ME:</SharePoint:AjaxDelta>-->
Hope it helps.
