building SDI type application using WPF and XAML

Hi,

I am using WPF-XAML to build an n-tier application which will behave like VB/C# style SDI application where we used to have one Parent window and all Child window associtated with the Parent window. Can you please tell me which Property of tag I need to modify for this behaviour.

I am using a TreeView(populate from the DB) in a UserControl which I will be using for Menu So my main window will always have UserControl and Form contents(on RHS side) is that correct approach for a Menu driven application?

I am new to WPF so struggling a bit to get into it. Please let me know if you have any hints and pointer on it for me.
