	The grid lines and ruler lines can not be aligned. I set GridSizeX = "10" GridSizeY = "10" GridOffsetX = "0" GridOffsetY = "0", the alignment is shown in the design interface, but after I run the program, I shifted 0.5 right. Then, I set GridOffsetX = "- 0.5" GridOffsetY = "- 0.5" and the grid line is shifted by 0.5 to the left. How to make the grid line alignment ruler scale?

	Zero offsets work for me. If it looks correct in designer but not in runtime, check if application's startup code isn't setting different values, or loading an older diagram file (where grid properties are stored as well).

I checked the code,There are no other places to set different values.And I've compiled my code from scratch. Still the same problem.Isn't the unit where I set the diagram is mm?

	The Xaml shows diagram's MeasureUnit is Millimeter, but the ruler's Unit isn't shown there. Please attach a test project that reproduces the problem.

The initial setting offset is 0, the grid line alignment, run once, the design interface grid line will not be aligned. Need to set offset for other values, and then set to 0, the design interface will be aligned. But when running, will not be aligned.

	It's caused by the control not redrawing the grid but just scaling a cached Visual, and some offset is added when you switch to millimeter which starts to scale too. For time being you can fix it by calling InvalidateBackground to redraw the grid, both when the window is loaded and after zooming - Code private void MainWindow_Loaded(object sender, RoutedEventArgs e) { Diagram1.InvalidateBackground(); } private void ButtonBase_OnClick(object sender, RoutedEventArgs e) { Diagram1.ZoomFactor = Math.Min(1000, Diagram1.ZoomFactor + 50); Diagram1.InvalidateBackground(); } Regards, Slavcho
