By default, the AllowZoomWheelSurface property is False. The AllowZoomWheelSurface property specifies whether the user can zoom the surface by rotating the mouse wheel. The AllowScrollWheelSurface property enables or disables scrolling the control while rotating the mouse wheel.  The control fires the LayoutStartChanging(exSurfaceZoom) / LayoutEndChanging(exSurfaceZoom) event when the user zooms the surface. The Zoom property specifies the current zooming factor of the surface. The ZoomMin/ZoomMax property specifies the range of the surface's zooming. 

The following samples shows how you can prevent zooming the surface:

VBA (MS Access, Excell...)

With SwimLane1
	.AllowZoomSurface = 0
