How to change the look of a cell’s border

Use the Borders property of GridStyleInfo to change the style and the appearance of the grid cells border. Each border side of the cell can be configured individually with GridBorder value. There is a BorderMargins property to control margins on all four sides.

//Borders on all four sides of the cell.
GridStyleInfo style = this.gridControl1.RowStyles[1];
this.gridControl1.RowStyles[1].Borders.All = new GridBorder(GridBorderStyle.Solid, Color.Red, GridBorderWeight.Thin);
this.gridControl1.RowStyles[2].Borders.Right = new GridBorder(GridBorderStyle.Dotted, Color.LightBlue, GridBorderWeight.ExtraThick);
this.gridControl1.RowStyles[3].Borders.Bottom = new GridBorder(GridBorderStyle.Solid, Color.Pink, GridBorderWeight.Medium);
this.gridControl1.RowStyles[4].Borders.Left = new GridBorder(GridBorderStyle.DashDot, Color.LightGreen, GridBorderWeight.ExtraThick);
this.gridControl1.RowStyles[5].Borders.Top = new GridBorder(GridBorderStyle.DashDotDot, Color.Purple, GridBorderWeight.ExtraExtraThick);

//BorderMargins.
this.gridControl1.RowStyles[1].BorderMargins.Right = 20;
this.gridControl1.RowStyles[2].BorderMargins.Left = 22;
this.gridControl1.RowStyles[3].BorderMargins.Top = 24;
this.gridControl1.RowStyles[4].BorderMargins.Bottom = 26;
'Borders on all four sides of the cell.
Me.GridControl1.RowStyles(1).Borders.All = New GridBorder(GridBorderStyle.Solid, Color.Red, GridBorderWeight.Thin)
Me.GridControl1.RowStyles(2).Borders.Right = New GridBorder(GridBorderStyle.Dotted, Color.LightBlue, GridBorderWeight.ExtraThick)
Me.GridControl1.RowStyles(3).Borders.Bottom = New GridBorder(GridBorderStyle.Solid, Color.Pink, GridBorderWeight.Medium)
Me.GridControl1.RowStyles(4).Borders.Left = New GridBorder(GridBorderStyle.DashDot, Color.LightGreen, GridBorderWeight.ExtraThick)
Me.GridControl1.RowStyles(5).Borders.Top = New GridBorder(GridBorderStyle.DashDotDot, Color.Purple, GridBorderWeight.ExtraExtraThick)
