Remarks
The CustomDrawCardFieldCaption event fires each time a card field caption needs to be repainted. The event enables you to paint such elements manually, or to modify your element’s settings before it is painted in the default manner. See the Custom Painting Basics and Custom Painting Scenarios topics for information on using custom draw events.

Never change cell values or modify the control’s layout on this event, or any other event designed to tune the control’s appearance. Any action that causes a layout update can cause the control to malfunction.
