Getting the window which contains a usercontrol

I have a user control hosted on a Window. The user control is actually
within a grid which is within a border.

When I call MessageBox.Show, from a button on the user control, the first
parameter I want to pass is 'owner'. How can I determine the "winodw" that
the user control is on. Is there a property of UserControl?

Thanks,
Michael

You can navigate the logical tree using the Control class' "Parent"
property. This will allow you to retrieve the top window quite easily
(for example, get the parent recursively until you find one of type
"Window".) Also, the LogicalTreeHelper class has static methods to help
you navigate this tree, but it doesn't bring much more in your case than
the "Parent" property.

You can also get the main window from everywhere in your application
using App.Current.MainWindow. However, if you have multiple windows,
this may not be the right one.

If you pick up my library at :

All you need to do is:

FrameworkElement fe = BaseWPFHelpers.Helpers.SingleFindInTree(mysender, new
FinderMatchType(typeof(Window)));
if(fe != null)
{
}
