I tried the UpdatePanel as you suggested, you are right, it doesn't work in an UpdatePanel either. Does this mean there is no way to use this within an RadAjaxPanel?
What I mean is... Is there some way to have the GoogleMap Control within an RadAjaxPanel do a complete reload/refresh? I'm not looking to refresh parts of this control, just be able to refresh the whole map control each time ajax request of the parent RadAjaxPanel is required?
Alternatively I've also found I could work around this by nesting the control within another page and use an iframe. If I do this, I need someway to show a LoadingAjaxPanel while the iframe is refreshed/reloaded. Is there someway to do this with an iframe (I have another post on this) ?
