Public static readonly DependencyProperty EnableDragProperty = DependencyProperty.RegisterAttached( / the window back onto the screen if part or all of it wasn't visible. / Essentially, it searches up the visual tree to find the first parent window, then calls '.DragMove()' on it. / Intent: Add this Attached Property to any XAML element, to allow you to click and drag the entire window. It would be more intuitive from the users point of view if the window slid quickly back into the visible area rather than just skipping back into the visible area, but at least this method gets the right results. Var bottomDockedHeight = (( - topDockedHeight) - ) Īs a bonus, you can implement your own drag'n'drop, and when the drag finishes, the window will be shifted back onto the screen. Var rightDockedWidth = (( - leftDockedWidth) - ) Var topDockedHeight = Math.Abs((Math.Abs() - Math.Abs())) Var leftDockedWidth = Math.Abs((Math.Abs() - Math.Abs())) Private static List GetTaskBarLocationPerScreen()įoreach (var screen in Screen.AllScreens) If this list is empty, then the taskbar is set to 'Auto Hide'. / Returned location of taskbar on a per-screen basis, as a rectangle. Var intersection = Rectangle.Intersect(taskBar, windowRect) While (windowRect.IntersectsWith(taskBar)) Keep on shifting the window out of the way. Rectangle windowRect = new Rectangle((int)window.Left, (int)window.Top, (int)window.Width, (int)window.Height) If taskbar is set to 'auto-hide', then this list will be empty, and we will do nothing. Var taskBarLocation = GetTaskBarLocationPerScreen() Window.Top = SystemParameters.VirtualScreenHeight + SystemParameters.VirtualScreenTop - window.Height If (window.Top + window.Height > SystemParameters.VirtualScreenTop + SystemParameters.VirtualScreenHeight) Window.Left = SystemParameters.VirtualScreenWidth + SystemParameters.VirtualScreenLeft - window.Width If (window.Top SystemParameters.VirtualScreenLeft + SystemParameters.VirtualScreenWidth)

Note that 'window.BringIntoView()' does not work. Public static void ShiftWindowOntoScreen(Window window) / - Shift the window away from overlapping the task bar. / - Shift the window onto the visible screen. This answer has been tested in a large scale real world application.Ĭall this from any attached property to shift the window back onto the visible screen: public static class ShiftWindowOntoScreenHelper
