Gets a value indicating whether the mouse pointer passes over the painted row header cell.
true if the mouse pointer passes over the painted row header cell; otherwise, false.
The VGridControlBase.CustomDrawRowHeaderCell event allows you custom paint the row header cells based on their state (hot-tracked, focused etc). Read the HotTrack property value to determine if the processed row header cell is hot-tracked (the mouse pointer is hovering over it).
You can also use the CustomDrawRowHeaderCellEventArgs.Pressed property to determine whether the painted row header cell is pressed.
