	When I initialize, set Diagram.Zoomfactor to 632, grid will be biased.I have already called Diagram.InvalidateBackground (),but it does not work.I have uploaded the demo source.

	InvalidateBackground won't work before the diagram's template is applied. Set zoom factor from the Window.Loaded event handler and it will align the zoomed grid correctly - Code public MainWindow() { InitializeComponent(); Loaded += (s, e) => { Diagram.ZoomFactor = 632; }; } private void Diagram_OnZoomFactorChanged(object sender, EventArgs e) { Diagram.InvalidateBackground(); } private void Diagram_OnMouseLeftButtonDown(object sender, MouseButtonEventArgs e) { Diagram.ZoomFactor = Math.Min(1000, Diagram.ZoomFactor + 10); } Regards, Slavcho
