Getting position/width/height of MainWindow [duplicate]

Answer 1

But, you should check "WindowState". In "Maximized" state properties "Left" and "Top" keep the values of the window in it's normal state. Window position in "Maximized" state discribes here: How can I find the position of a maximized window?

Answer 2

You can access the position of the main window all over your code via Application.Current.MainWindow.Left and Application.Current.MainWindow.Top, respectively. Hope this will help.
