I have a very urgent problem with a lot of Infragistic Controls.

In Short:

- UltraPanels doesn't redraw and resize correctly
- UltraGrid, UltraTree doesn't redraw and resize corretly
...if the Control-Level is too deep

Longer:

For a bigger project i'm designing a lot of UserControls, used as "Modules" in our software. Now, A Form will have some Panels to structure the space and to use splitters. On a Panel there might be TabControl. On a Tab a UserControl will be placed. This UserControl again may contain Panels which contains another UserControl which creates more UserControls with Panels and Grids...

At some (not that deep) level, Infragistics-Controls will stop working correctly in terms of Anchors, FillStyle and Redraw/Paint-Events. It took me a while to figure out, that this is not a problem in my code but with the controls.

What i've tried so far:

I have seen the resize-problem with 2010.2.2026 (an UltraGrid and an UltraPanel did not resize)

I then updated to 2010.2.2151 - now the old problem still exists but i saw a new Problem (Redraw and Resize-troubles on an other form.

Then i installed 2010.3.1000 (was on our local sever for a while) but had troubles upgrading the Solution

So i got 2010.3.2107, updated the solution trouble-free, but saw the exact same errors. Nothing changed.

So i started build up a little Test-project showing the problem. I have attached it.

What i need:

I really need a solution for this problem.
Please tell me soon in which Version this error is fixed or, if not, please provide me with a Hot-Fix or an early SR or something. I need to go on building modules and the application and very soon i have to present this application.

Thanks a lot for quick help
