Access parent window control WPF

Question

I have two windows:

ListItemWindow

(parent) that contain ocItems as ObservableCollection

DetailItemWindow

I called DetailItemWindow from ListItemWindow (DetailItemWindow.ShowDialog())

From DetailItemWindow How can I access to ocItems ?

When you open a window in WPF the parent isn't automatically set. You have to set it manually between instantiating it and calling .ShowDialog. — Bradley Uffner, May 06 '15 at 13:56
@m_wilcynski has an answer below that shows how to do it. It's just a property on the window that you can set before displaying the dialog. Basically, `OtherWindow.Parent = this` if called from the code behind of a window. Things get trickier if you are using MVVM. — Bradley Uffner, May 07 '15 at 18:55

Why not pass parent Window in constructor to child Window? It doesn't violate MVVM at all, Views can know each other if they're dependant.

private ListItemWindow parent;

public DetailItemWindow(ListItemWindow window){
   this.parent = window;
}
