I am not sure I understand your problem.
The grid''s scrollbar and the form''s scrollbar are completely unrelated. So, no properties you set in the grid will affect whether or not your form''s scrollbar is visible.
If you set VScrollbarBehavior = AutoScroll, the behavior you should see is that the vertical scrollbar is not displayed when the grid''s clientarea is large enough to show all rows in the grid, and the vertical scrollbar should be visible when there are some grid rows that cannot be displayed in the grid''s clientarea.
This means that if the grid is anchored on all 4 sides, the grid''s vertical scrollbar should be displayed as your make the form tall enough to see all the rows in the grid.
Can you post a little sample project showing the problem? You can email a zip to
