I am currently working on a WPF application with MVVM and Prism v 5.7.0. At some point I am using the default mechanism of the Prism to display a popup window. Inside the popup window I an having a TreeViewAdv control. The problem is that the width and the height of the window are not the default (as needed to display the window content).
As you can see in the demo that I sent you, when you click the first button that displays a popup window with content a UserControl that contains the TreeViewAdv (PopupWindowTreeViewAdvUC file) the width and the height of the window are not the default. In the contrary, when you click the second button that displays a popup window with content a UserControl that contains the native TreeView (PopupWindowTreeViewUC file) the width and the height have the default values. I haven't set the UserControl.Width and the UserControl.Height of the PopupWindowTreeViewAdvUC on purpose, because if I give them specific values then when I resize the popup window the UserControl will not stretch with the window.
