Controls which resize themselves !

[Martin]

Hi all !

I use Visual Studio .NET 2005 SP1 (+ Updates for Vista) on Windows
Vista. I have a strange problem in a WinForm application.

In a UserControl, which inherit another UserControl (simply contains a
SplitterPanel), I've added controls (most of them are TextBox with the
property Anchors set to Left and Right) to Panel2. All theses controls
fits in the UserControl and when I resize it, all the controls have
the correct behavior. My problem occurs when I compile the solution.
After a sucesseful compilation, if I re-open (of may refresh itself)
the Form Designer, all my controls are out of the UserControl!

Does someone have seen that before? Any ideas?

Thanks for your help!

Here a piece of code that I use to reproduce the problem above. Could
someone give it a try ?

Thanks !
