Use the HeaderForeColor and HeaderBackColor properties to defines the colors of the control's header bar. If the Def(exHeaderForeColor) property is not zero, it defines the foreground color to paint the column's caption in the header area. Use the LevelKey property to display the control's header bar using multiple levels. If the control displays the header bar using multiple levels the HeaderHeight property gets the height in pixels of a single level in the header bar. Use the HeaderVisible property to specify whether the control's header bar is visible or hidden. The control's header displays multiple levels if there are two or more neighbor columns with the same non empty level key. Use the ForeColor property to specify the control's foreground color.
