If you want the big panel on the left to be the content then you would put that control into the Content property (where the TextBox is in the above snippet) and leave the other two in a split pane on the right. If this is not what you are trying to accomplish then please provide more information about your layout requirements and I can try to help you.

And is it possible to do this layout without the using of this "big panel". for example i want that all content is floatable and dockable. when i put something in the content of xamDockManager it wont have this features. but when i leave the content blank and put all in the panes of xamDockManager i have always this blank area of the xamDockManager content.isnt it possible to let the panes fill the whole area? i remember that there was a flag in UltraDockManager (winForms) "LayoutStyle" wich could be set to "Fill Container" so that when you do something like that 

 you only have this single pane in your dockmanager and no Splitter on the right, because theres nothing. I hope you understand my problem. 

Thanks

There's another thread discussing having a Fill layout style in xamDockManager. Basically that feature is not available in the current version. I would recommend submitting a suggestion for that feature and include as much details about your requirements as possible. In that sample you could have replaced the TextBox with a DocumentContentHost but that's not quite the same as filling with dockable panes - that will create a tabbed document similar to VS (except we actually allow you to drag panes into and out of the document area and like our tabbed mdi manager we allow nested groups).
