I tested the scenario you have described, however, I was no able to reproduce the problem you experience. Please, send me a simple running application which reproduces the problem and a list of simple steps for reproducing it so that I can test, research it and do my best to help you.
Looking forward to receiving your reply.
Kind regards,

"sys.webforms.pagerequestmanager is null or not an object"
Any ideas as to what causes this? I am guessing that its probably something to do with my web.config but I am not sure.

this._owner.GridDataDiv is null or not an object
Any ideas? Here is the aspx code that looks simple enough but is the cause of the problem.

"sys.webforms.pagerequestmanager is null or not an object"
Just for a little background, I am trying to place an AjaxPanel on the site but am getting an error. I did not have this problem in some of my other applications I have made.
I removed this line from the web.config and the error went away, but I don't know if this is what I should have done.
<xhtmlConformance mode="Legacy"/>
Can I expect to see this new fix that you are going to release in a week fix this issue?
Please refer to the following blog post by Scott Gu: Gotcha: Don't use <xhtmlConformance mode="Legacy"/> with ASP.NET AJAX

I've got the RadGrid as part of a seperate usercontrol which I then load inside the RadToolTip.
The problem is that the style/skin of the control seems not to load correctly.
Any help would be appreciated
The problem with the skin of the RadGrid is actually caused by MS AJAX, on top of which all Prometheus cotnrols are built. The MS AJAX engine is not so advanced as to register <link> CSS tags coming from an AJAX request. Thus, the calender skin is simply not registered and lost.
To overcome the problem you should manually add a reference to the grid skin to the <head> of the page, e.g.:
<link rel="stylesheet" type="text/css" href="Skins/Default/Grid.Default.css"></link>
