RadAjaxPanel question concerning invisible panels and controls

I understand the part about RadAjaxPanel ajaxifying all controls within it's tags but does it ajaxify invisible controls? Say you have five asp panels within a RadAjaxPanel that you toggle visibility on based on link button clicks. If only one panel is visible at a time, does the RadAjaxPanel ajaxify ALL of the five panels' controls on say, a button click contained within the visible panel OR does it ajaxify just the panel that is visible and therefore just the controls contained within the visible panel?

Tooltip with grid paging issue

I am having difficulty on a tooltip with grid and this grid has pagination.

Scenario:
Parent page -> radgrid with tooltip -> load ascx for tooltip
Tooltip (ascx) -> radgrid with pagination

If tooltip is shown and next page is clicked, nothing happens since it always call ajaxupdate and not the pagination event or the needdatasource event of the grid on the tooltip (ascx)

Kindly advise on this scenario.

Thanks.

ASP.NET Quadrant/Semi-Circle Gauge

Is there a way to configure the RadRadialGauge for quadrant-style or semi-circle gauges. The Silverlight gauges have this option, but I don't see it for the ASP.NET gauge controls.

Multi-Column RadComboBox Not Populating Correctly in RadWindow

Using the RadComboBox for the first time, I first implemented it on a test page to ensure I figured out how to implement it properly. After a little trial & error, I got it working, displaying 2 columns of a DataTable as is shown in the first attachment.

Now I'm trying to implement it for real, which happens to be in a RadWindow dialog box. Yet, as the 2nd attachment shows, it's not populating in the same way. Not only does it only have just one column, but even the basic appearance of the collapsed RadComboBox is different:

In the test case it appeared grey in colour
In the RadWindow it appears white in colour, indistinguishable from the standard DropDown ListBox

What do I need to do with the RadWindow implementation to get it to populate correctly?
