You can use the C1Magnify.MagnifierShowing event to change the Magnifier Window before the window is displayed. In the event, you can use different settings in different controls. Also, you can cancel showing the Magnifier Window when the e.Cancel property is set to True.
The following code shows a rectangular Magnifier window for a TextBox. It does not show the Magnifier window for NumericUpDown, but it shows a circular Magnifier window for other controls.
