UWP Title Bars and Start Bar Triggers

Never mind I figured it out,
add an event:-

Windows.Devices.Input.MouseDevice.GetForCurrentView().MouseMoved += MouseController;

/*********************************************************************************************

  • Function Name : MouseController
  • Description : event setup by the constructor
  • ******************************************************************************************/
    private void MouseController(Windows.Devices.Input.MouseDevice sender, Windows.Devices.Input.MouseEventArgs args)
    {
    outputPos.X += args.MouseDelta.X;
    outputPos.Y += args.MouseDelta.Y;
    if (outputPos.X <= boundry.X) outputPos.X = boundry.X;
    if (outputPos.Y <= boundry.Y) outputPos.Y = boundry.Y;
    if (outputPos.X >= boundry.X + boundry.Width) outputPos.X = boundry.X + boundry.Width;
    if (outputPos.Y >= boundry.Y + boundry.Height) outputPos.Y = boundry.Y + boundry.Height;
    }
