Some general Forms Designer options are available from the Options window:
Choose Tools > Options > Windows Forms Designer > General.
Set the following options:
GridSize – Choose the width and height of the sizing grid
ShowGrid – Set to True if you want to see the sizing grid while painting GUI screens
SnapToGrid – Set to True if you want design elements to snap to the sizing grid.
These options apply when designing any GUI element. The options can be modified for individual GUI elements in the Properties tab for that element.
