Null argument exception with TabWorkspace in C#

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   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?

	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.
