To reproduce: please refer o the attached sample project: 1.Click the left button. A new row will be added to the left grid and the grid will scroll to it. 2. Move the scrollbar back to the top and sort the ID column. 3. Click the left button again. A new row will be added but the grid won't scroll to it. Perform the same steps with the right grid. The grid scrolls as expected when you add a new row in a sorted grid. Workaround: use the Rows.Add method instead of Rows.AddNew.
