The GridRowCellState enumeration contains row cell states for the Grid Control's appearance customization events. When handling an appearance customization event (for instance, GridView.RowStyle, GridView.CustomDrawCell, etc) you can read its State parameter to customize the appearance settings of the painted element (a cell or row) depending upon its state.
The GridRowCellState enumeration has the System.FlagsAttribute attribute that allows a bitwise combination of its member values.
