当窗口最大化模式时，如何移动（拖放）wpf窗口

Question

How to move (Drag and Drop) wpf window when windows is maximized mode. I am using below code but when window is maximized mode then its not working.

 private void Window_MouseMove(object sender, MouseEventArgs e)
    { 
       if (e.LeftButton == MouseButtonState.Pressed)
        {
            this.DragMove();
        }
    }

How to fix this problem?

Answer 1

Use PreviewMouseLeftButtonDown Event, Change WindowState to Normal by code and after it apply DragMove Method.

   private void Grid_PreviewMouseLeftButtonDown(object sender, MouseButtonEventArgs e)
        {            
            if (WindowState == WindowState.Maximized)
            {
                WindowState = WindowState.Normal;
            }

            DragMove();           
        }

When subscribe to Mouse move evet you can change window enter code heresize and location. For example

`if (this.WindowState == WindowState.Maximized)
   {
       this.Width = this.ActualWidth;
       this.Height = this.ActualHeight;
       this.Left = 0;
       this.Top = 0;
       this.WindowStartupLocation = WindowStartupLocation.Manual;
       this.WindowState = WindowState.Normal;
    }`
