The ToolStripRenderer.DrawDropDownButtonBackground(ToolStripItemRenderEventArgs) method provides the entry point to the rendering code for the background of a System.Windows.Forms.ToolStripDropDownButton. Use this method to draw the background of a drop-down button when overriding the ToolStripDropDownButton.OnPaint(PaintEventArgs) method, or to force the background of a drop-down button to be drawn in a custom System.Windows.Forms.ToolStripRenderer. To change the way the background is rendered, override the ToolStripRenderer.OnRenderDropDownButtonBackground(ToolStripItemRenderEventArgs) method in a class derived from System.Windows.Forms.ToolStripRenderer.
