Question

So I have a user control within a window. I need to be able (from user control) to retrieve the parent window left and top (in order to locate a new popup I’m opening from the child). I’m trying to do this by referencing the UserControl .Parent property but doesn’t seem to work.

Any idea? Thanks!

Are you using MVVM? Are you concerned about writing code in the code behind? .Net 3.5 or 4.0?

From the UserControl Code behind you could use:

Window parentWindow = Window.GetWindow(userControlReference);



public partial class UserControl1 : UserControl
{
    public UserControl1()
    {
        InitializeComponent();

        Loaded += new RoutedEventHandler(UserControl1_Loaded);

        //Window parrentWindow = Window.GetWindow(this);//don't add here the value will be null
    }

    void UserControl1_Loaded(object sender, RoutedEventArgs e)
    {
        Window parrentWindow = Window.GetWindow(this);
    }
}
