在DataGridView的CellPainting事件中，加入如下代碼
private void dataGridView1_CellPainting(object sender, DataGridViewCellPaintingEventArgs e)
{ href="file:///C:/DOCUME~1/ADMINI~1/LOCALS~1/Temp/msohtml1/01/clip_filelist.xml" rel="File-List" />
if (e.RowIndex >= 0 && e.ColumnIndex == -1)
{
Rectangle newRect = new Rectangle(e.CellBounds.X, e.CellBounds.Y, e.CellBounds.Height, e.CellBounds.Height);
//新建一個圖標
System.Drawing.Icon ico = new Icon("F://xx.ico");
using (Brush gridBrush = new SolidBrush(this.dataGridView1.GridColor),
backColorBrush = new SolidBrush(e.CellStyle.BackColor))
{
using (Pen gridLinePen = new Pen(gridBrush,2))
{
// Erase the cell.
e.Graphics.FillRectangle(backColorBrush, e.CellBounds);
//劃線
Point p1 = new Point(e.CellBounds.Left+e.CellBounds.Width, e.CellBounds.Top);
Point p2 = new Point(e.CellBounds.Left+e.CellBounds.Width, e.CellBounds.Top+e.CellBounds.Height);
Point p3 = new Point(e.CellBounds.Left,e.CellBounds.Top+ e.CellBounds.Height);
Point[] ps = new Point[]{p1,p2,p3};
e.Graphics.DrawLines(gridLinePen,ps);
//畫圖標
e.Graphics.DrawIcon(ico, newRect);
//畫字符串
e.Graphics.DrawString("123", e.CellStyle.Font, Brushes.Crimson, e.CellBounds.Left + 20, e.CellBounds.Top, StringFormat.GenericDefault);
e.Handled = true;
}
}
}
}
例外還有其他方法供參考，也是在DataGridView的CellPainting事件中
href="file:///C:/DOCUME~1/ADMINI~1/LOCALS~1/Temp/msohtml1/01/clip_filelist.xml" rel="File-List" />
//”A”顯示在-1（即RowHeader）列之上
if (e.RowIndex >= 0 && e.ColumnIndex == 0)
{
e.Graphics.DrawString("A", this.dataGridView1.Font, Brushes.Red, 20, e.CellBounds.Top + 5);
}
//”A”則被-1（即RowHeader）列覆蓋。
if (e.RowIndex >= 0 && e.ColumnIndex == -1)
{
e.Graphics.DrawString("A", this.dataGridView1.Font, Brushes.Red, 20, e.CellBounds.Top + 5);
}
//XX圖片在-1（即RowHeader）列之上
if (e.RowIndex >= 0 && e.ColumnIndex == 0)
{
Image img = Image.FromFile(@"F:/xx.bmp");
e.Graphics.DrawImage(img, 0, e.CellBounds.Top);
}
//XX圖片被-1（即RowHeader）列覆蓋
if (e.RowIndex >= 0 && e.ColumnIndex == -1)
{
Image img = Image.FromFile(@"F:/xx.bmp");
e.Graphics.DrawImage(img, 0, e.CellBounds.Top);
}
//XX圖片被-1（即RowHeader）列覆蓋
if (e.RowIndex >= 0 && e.ColumnIndex == -1)
{
Image img = Image.FromFile(@"F:/xx.bmp");
e.Graphics.DrawImage(img, e.CellBounds.Left, e.CellBounds.Top);
}
//XX圖片被0列覆蓋
if (e.RowIndex >= 0 && e.ColumnIndex == 0)
{
Image img = Image.FromFile(@"F:/xx.bmp");
e.Graphics.DrawImage(img, e.CellBounds.Left, e.CellBounds.Top);
}
