Example throw exception

[Jan]

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

The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases.

and stack trace

[HttpException (0x80004005): The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases.]
   System.Web.UI.ControlCollection.Add(Control child) [phone]
   Telerik.Web.SkinRegistrar.RegisterCssReference(Page _page, Control _control, String _url) +619

[HttpException (0x80004005): Please, see whether wrapping the code block, generating the exception, within RadCodeBlock resolves the error.]
   Telerik.Web.SkinRegistrar.RegisterCssReference(Page _page, Control _control, String _url) +724
   Telerik.Web.SkinRegistrar.RegisterCssReferences(ISkinnableControl _control) +1182

Do you have any clue, what I'm doing wrong?

Many thanks!

I found it.

I have all the code in HEAD placeholder. Silly me.  Sorry guys!

Hello Jan,

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

Regarding my last post I would like to apologize for being stupid.

I have the same exception, but I Added the grid in the Sharepoint web part 

 

I did not add any code behind  , I just added to the aspx the following : 

<telerik:RadGrid ID="RadGrid1" runat="server" >

</telerik:RadGrid>​

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.
