我想修改列的网格线的颜色，就是竖着的线的颜色，而且想设置每列之间的线的颜色不一致，我式了一下gridcolor貌似不行..麻烦哪位大虾指导下我，谢谢~

Answer 1

// Change the Border and Gridline Styles in  the Windows Forms DataGridView ControlSamples:  
 
this.dataGridView1.GridColor = Color.BlueViolet;  
this.dataGridView1.BorderStyle = BorderStyle.Fixed3D;  
this.dataGridView1.CellBorderStyle = DataGridViewCellBorderStyle.None;  
this.dataGridView1.RowHeadersBorderStyle = DataGridViewHeaderBorderStyle.Single;  
this.dataGridView1.ColumnHeadersBorderStyle = DataGridViewHeaderBorderStyle.Single; 

Answer 2

只能自己画了，datagridview绘制的时候，是按单元格来绘制的矩形，按你的要求就是绘制矩形的左右边框颜色不同了
给你一段代码是绘制行头和列头的       protected override void OnCellPainting(System.Windows.Forms.DataGridViewCellPaintingEventArgs e)
       {
           Color mLinearColor1 = Color.FromArgb(248, 250, 251);
           Color mLinearColor2 = Color.FromArgb(196, 207, 224);
           Color mGridColor = Color.FromArgb(120, 147, 191);  //网格线的颜色
           Color mHasFocusedColor = Color.DarkCyan;          //控件的焦点框颜色 
           Rectangle Rect = new Rectangle(e.CellBounds.X - 1, e.CellBounds.Y, e.CellBounds.Width, e.CellBounds.Height - 1);
           LinearGradientBrush LinearGradientBrushs = new LinearGradientBrush(Rect, mLinearColor1, mLinearColor2, LinearGradientMode.Vertical);                     try
           {
               if (e.RowIndex == -1 || e.ColumnIndex == -1)
               {
                   e.Graphics.FillRectangle(LinearGradientBrushs, Rect);
                   e.Graphics.DrawRectangle(new Pen(mGridColor), Rect);
                   e.PaintContent(e.CellBounds);
                   e.Handled = true;
               }
           }           catch
           { }
           finally
           {
               if (LinearGradientBrushs != null)
               {
                   LinearGradientBrushs.Dispose();
               }           }           /*不显示焦点颜色*/
           this.DefaultCellStyle.SelectionBackColor = Color.Transparent ;
           this.DefaultCellStyle.SelectionForeColor  = Color.Black ;
           base.OnCellPainting(e);
       }
