WinForms Data Grid - Hide vertical lines between certain columns

This example demonstrates how to hide vertical grid lines for specific columns by handling the grid.Paint event (draw vertical lines with cell background color).

Note

Alternative Method: Set the ShowVerticalLines property to DefaultBoolean.False to hide all vertical lines, and draw vertical lines inside certain cells by handling the CustomDrawCell event.
