I'm adding a tabControl to a grid with
<
igWindows:XamTabControl Grid.Row="0" Name="xamTabControl1" AllowMinimize="False" >
But all the content that I add to my TabItemEx appears to be minimized. This is both in the designer and at runtime. Now, I have several XamComboEditor's in the TabItemEx, and if I comment one of them out the designer redraws the window and everything looks fine. When I run it, however, everything is minimized again.
Replacing the XamTabControl with a plain ol System.Windows.Controls.TabControl corrects the issue entirely.
I am not aware of any problems like you describe. Can you post a sample project that demonstrates the issue you are encountering?
