I am trying to create MDI windows in WPF, similar to what we have in Winforms. How can I do this?

Not clear.

Another very good solution on codeplex is AvalonDock[^] - You'll be able to create a flexible UI similar to the Visual Studio tabbed MDI.

Voted 5, as I think it adds to the thread and gives the OP an alternate option.

Thank you Nishant!

Agreed with Nish. Good answer.

A 5, but again, I added my Answer (please see) with advice not to do that.
I think you already agreed with that.
Technically speaking, Answers by Espen and Nishant are correct.

But do yourself a favor, listen to my good friendly advice: don't do MDI!
There are not so many UI designs that are so inconvenient and cumbersome! Everyone I know (and I know very many computer people, not just developers) hate such user experience and well agree with me. You cannot find any serious company or UI developer using such design.

Instead, use tabbed UI, or dockable (or combined), or controlled by tree/list view TOC-page style, or folding panels or something like that.

My 5, I agree, and AvalonDock provides the features required for a tabbed MDI :)

Thank you, Espen.
Tabbed MDI is quite possible, better be without MDE part :-)
The problem if more then one-level hierarchy design is practically important. It's more about understanding industrial design then technology. Recently my colleague designed to put another tabbed interface inside a tab page and asked me for a quick fix. It was very confusing, so I replaced inner part with list controlling panel content (TOC-page interface), good for quick fix, but maybe not stilistically consistent. Levels of hierarchy should be visually distinct.

I agree with SA. Trying using dashboard like controls (tab, docks etc).
They allow you to show much more data on the same page.

AvalonDock does just that - allowing you to create a UI similar to Visual Studio 2010
Sergey Alexandrovich Kryukov 20-Feb-11 13:51pm    
...Which is nothing like MDI.
Do you have good experience with AvalonDock? I was trying to find something for WPF a while ago.
If you do, what's your assessment of its quality?
(Last time I implemented docking UI as based on Weifen Luo docking library (used in SharpDevelop): I had to put my parches, replace one part and ignore some others to put it to work...)

Thank you.

I used to use it before DevExpress came up with an alternative for WPF and SilverLight - I found it quite useful :)
Sergey Alexandrovich Kryukov 20-Feb-11 14:50pm    
Thank you. So, no major defect, qualify or performance problems?
How about DevExpress, this is all proprietary, commercial close-source, right?
