Allowing the User to Zoom the Display of the Component

You can allow the user to change the scale of the display of the Spread component, in other words to zoom in or zoom out. Use the AllowUserZoom property of the FpSpread class. This allows the user to zoom in or out by pressing the Ctrl key and turning the mouse wheel. The user can zoom in up to 400% and out to 10% of the default display. The scroll bars are unaffected by zooming; only the corner, headers, and data area change their appearance with zooming.

Using the Spread Designer

Select the View menu and then the Zoom option.
Set the percentage.
From the File menu choose Apply and Exit to apply your changes to the component and exit the Spread Designer.
