I am trying to use the CodeJock controls in a C# application. When I try to set the TabWorkspace.IgnoreFlickersOnActivate property, it crashes with a null argument exception. TabWorkspace is null. How can I create it? Also, in some cases the .Options property is null, but not in other cases. What's going on here?

Hi,

Do you call CommandBars.SetMDIClient ?

Calling SetMDIClient fixed the problem where the .TabWorkspace property was null on the MDI container. However, I still have the problem on the MDI child windows where the .Options property - and others - are null. Calling SetMDIClient didn't help.

I figured out what the problem was. I read some other forum articles and discovered that I need to initialize the control after setting the MDIParent property, not before. It works now.
