The scroll bar may be there but you cannot see it because it is being hidden
by another control?
In my case, this is usually related to an incorrect Docking of the control.
Go into the designer and right click the grid, select Bring To Front or set
Dock to none and use anchoring to resize the control. Anchoring Top, Left,
Bottom, Right can produce the same result as DockStyle.Fill
You can also get an idea of where the control is laid out by looking at the
size grips when the control is selected in the designer. The grips not
associated with a corner of the control should be centered in the width and
height of the control. Or compare the Size of the Control to that of the
container. Make sure things add up.
