datagridview 設置行號(轉載來息互聯網)

可以在DataGridView的RowPostPaint事件中进行绘制。
代碼如下:

privatevoiddataGridView1_RowPostPaint(objectsender,DataGridViewRowPostPaintEventArgse)
{
Rectanglerectangle
=newRectangle(e.RowBounds.Location.X,
e.RowBounds.Location.Y,
dataGridView1.RowHeadersWidth
-4,
e.RowBounds.Height);

TextRenderer.DrawText(e.Graphics,(e.RowIndex
+1).ToString(),
dataGridView1.RowHeadersDefaultCellStyle.Font,
rectangle,
dataGridView1.RowHeadersDefaultCellStyle.ForeColor,
TextFormatFlags.VerticalCenter
|TextFormatFlags.Right);
}
}
}
