Ajax postback of single dock

[apb]

I have a portal-type application that allows the creation of various "portlets".

Each portlet consists of a dynamically created RadDock, which contains a dynamically created RadAjaxLoadingPanel and RadAjaxPanel, which contains a dynamically loaded user control (ascx).

Dock
|--RadAjaxLoadingPanel
|--RadAjaxPanel
   |--UserControl

When the user control inside the dock initiates a postback the update panel works as expected, centering over the individual Dock.

However, when the Dock initiates the postback, say by clicking a DockCommand button, the RadAjaxLoadingPanel doesn't display.

So, my question is:

Is there a client-side way for the Dock to tell the control inside it to initiate an action? 

This would actually be useful for other situations as well.

You could try to use RadAjaxManager instead RadAjaxPanel, create a  custom command and in its client-side handler to initiate ajax via JavaScript.
