What you're describing tells me you should NOT be using MDI at all.

MDI stands for "Multiple DOCUMENT interface". This means that you're opening multiple documents for editing in multiple copies of the same editor window. Kind of like opening multiple Notepad windows all in the same application.

What you're talking about is nothing like this, therefor you should NOT be using MDI at all.

By the way, you can't do what you're describing in the Mdi container control. It doesn't support being split.

Actually,i don't care if the application is mdi or not,i only want let three child forms activation state mutual exclusion,how to achieve this function?

Your "function" isn't described very well but it sounds like you only need a couple of split containers, one vertical and one horizontal, one inside one of the panels of the other. That's it.
