    Hi, I have a RadAjaxLoadingPanel which automatically fires when my radgrid needs a data source. Great.
    However, in my NeedDataSource event, I have a condition set to tell the code that it might not need to rebind.

    If multiviewContacts.GetActiveView.ID = "viewContactSelect" Then
         'Bind the radgrid
    else
        'Don't bother binding
    end if

    When my code doesn't need to rebind, the Loading Panel remains on the screen.

    Surely, there must be a simple way of removing the loading panel from server side, code-behind.  I just can't find it !


    I've looked at the demo http://www.telerik.com/help/aspnet-ajax/ajax-show-hide-loadingpanel.html but I don't want to have to add 25 more lines of javascript to my page just to hide the loading panel.

    ...and even then - I have the issue of calling that javascript from the code behind.


    Cheers,
    Scott

    I'd really appreciate an admin's input on this if possible.

    Hi Scott,

    Note that the appearance and hiding of the loading panel is handled entirely on the client. It would not hide only in case the request that it was shown for did not end successfully. Therefore, my advice is to check in Firebug or IE Developer toolbar whether the request to the server ends successfully and also if there are any client-side errors.
    In a correctly working scenario there would be no need to explicitly hide the loading panel if it was shown by an ajax setting.
