Force 1/3 width window in Windows 10 Tablet Mode

Question

In Tablet Mode, activating my window causes it to get full width, but our software is a utility program that really works with other programs and needs 1/3 to 1/4 width. Can I control how wide the window gets and also force sharing with the last app?

Answer 1

Try to use properties System.Windows.SystemParameters.PrimaryScreenWidth and System.Windows.SystemParameters.PrimaryScreenHeight which gets size Width and Height of display in pixels.

if (System.Windows.SystemParameters.PrimaryScreenWidth < 1500 && 
    System.Windows.SystemParameters.PrimaryScreenHeight < 800)//you should set your own parameters of your Window of Tablet
{                
   Application.Current.MainWindow.Height = Application.Current.MainWindow.Height/3;
   Application.Current.MainWindow.Width = Application.Current.MainWindow.Width/2;
}
