    I get the following script error when I have removed items form the RadSlidingZone:

    I have defined four slidingpanes in the slidingzone in the aspx file.
    In the InitComplete event method I have added two new panes and removed one exisiting pane.
    When I load the page, I get the error message.
    When I only add panes all working fine without the error
    Only when I have removed an existing pane the error occurs after page is loaded.

    I'm using the the telerik version 2011.2.712.35

    Any idea why the error occurs?

    Best regards,

    Hi Ralf,

    We are not aware of such problem and you are the first one to report it. I tried to reproduce the problem with the provided information but to no avail. Could you please open a formal support ticket and provide a sample fully runnable project replicating the issue so we can examine and debug it locally?

    For your convenience I have attached my sample page, could you modify it to a point where the problem occurs and send it back?

    All the best,
    the Telerik team

    Hello Dobromir,

    thank you for reply.

    I have checked your sample, and I have modified it by using my layout. I found out that the error occurs only in my solution. I have placed webparts inside the slidingpanes. And if I remove a pane containing a webpart, the error occurs. When I remove a slidingpane not containing a webpart but a table for example, the error doesn't occur. The page will be used in a SharePoint 2010 context, placed in LAYOUTS folder. Whe webparts will be connected together in the code (c# script inside the page), not via the WebPartManager.

    I will create a sample and open a support ticket then.

    Best regards,
