    As can be seen with my previous posts on problems I am having with the Docking controls, I decided, perhaps the simplest thing would be to step back from the application I'm building and create a test application.

    The first thing I did, was following the documentation, I created a simple page with a RadDockLayout, A RadDockZone, and a single button. In the code behind, I took the code strait out of the documentation for creating dynamic docks. I create a dock dynamically and add it to the RadDockZone.

    I ran this simple test page and clicking the button adds a new dock, dynamically created, to my DockZone. Yay! That part works great.

    Now, taking it a step further, all I added was a RadAjaxManager and using the designer, hooked up the button as a firing control and the RadDockLayout and RadDockZone as the targets.
    <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
                <AjaxSettings>
                    <telerik:AjaxSetting AjaxControlID="Button1">
                        <UpdatedControls>
                            <telerik:AjaxUpdatedControl ControlID="RadDockLayout1" />
                            <telerik:AjaxUpdatedControl ControlID="RadDockZone1" />
                        </UpdatedControls>
                    </telerik:AjaxSetting>
                </AjaxSettings>
            </telerik:RadAjaxManager>

    Now, when I run the page and click the button, there is no postback and a Dock appears in the DockZone. Yay ... er ... wait, no. Not Yay, because the Dock is broken. It can't be moved, the controls in the titlebar don't work, and I notice there is a Javascript Error on the page. I open up the error to take a peak and see:

    Line: 6
    Char: 31345
    Error: Object expected
    Code: 0
    URL: http://localhost:3521/TelerikDockTest/Default.aspx.


    So....it appears my issues have nothing to do with my application and there is some fundamental problem with using the AjaxManager to "Ajaxify" and event which dynamically creates a Dock.

    Now, what's interesting is if I click the button a couple of times, creating some docks, the error doesn't stop Docks from being created, they just come in "broken." If I then however click the refresh button on my browser, the docks I created are there, there is no error on the page, and I can move the docks and the controls in the titlebar work.

    So it seems that in order for a Dock to work correctly it has to be registered during a full page cycle (The Page_Init has to be called) and as far as I can tell there is no intuitive way to Ajaxify the dynamic creation of RadDocks.

    I do hope I am wrong, and if so, please guide me to what I need to change in order for this to work as expected.
