protected internal virtual void PaintHeader (System.Drawing.Graphics graphics, System.Drawing.Rectangle clipBounds, System.Drawing.Rectangle rowBounds, int rowIndex, System.Windows.Forms.DataGridViewElementStates rowState, bool isFirstDisplayedRow, bool isLastVisibleRow, System.Windows.Forms.DataGridViewPaintParts paintParts);
abstract member PaintHeader : System.Drawing.Graphics * System.Drawing.Rectangle * System.Drawing.Rectangle * int * System.Windows.Forms.DataGridViewElementStates * bool * bool * System.Windows.Forms.DataGridViewPaintParts -> unit

Protected Friend Overridable Sub PaintHeader (graphics As Graphics, clipBounds As Rectangle, rowBounds As Rectangle, rowIndex As Integer, rowState As DataGridViewElementStates, isFirstDisplayedRow As Boolean, isLastVisibleRow As Boolean, paintParts As DataGridViewPaintParts)
