    Hi... Im fiddling around with the fileexplorer. It works fine when i place the component on my Default.aspx. But when I put it in a usercontrol i get a JS error Pane is null or not an object. I cant do anything with the component and it is not drawn correct (missing icons, borders etc.

    Is there a workaround?

    Hello lkj,

    The RadFileExplorer control works without problems in user controls and you are the first that reports such a behavior. I suppose, however, that the user control in your case is partially updated  - by using RadAjaxPanel, UpdatPanel or RadAjaxManager. Please note that the RadFileExplorer control cannot be used in scenarios with nested callbacks. The control uses asynchronous callbacks in order to load its content and when two or more nested callbacks are initiated the result becomes unpredictable.
    If this is your case, you need to exclude the RadFileExplorer from the partially updated region. In case, however, your scenario is different, could you please open a new support ticket and send me a project that reproduces the problem? I will check it and do my best to provide a working solutions as soon as possible.

    I hope this helps

    All the best,
    Fiko
