新建一个WinForm项目,在工具栏里拖一个dataGriView到窗体中,默认名称为dataGridView1,把数据源添加到dataGridView1中,运行,看到dataGriView1有数据显示,但没有行编号,所以我们需要添加一列,用来显示行号,以便我们知道这是第几条记录。选中dataGriView1,然后在属性列表的事件选择RowPostPaint事件,双击后添加事件处理函数,代码如下:

privatevoid dataGridView1_RowPostPaint(object sender, DataGridViewRowPostPaintEventArgs e){    //自动编号,与数据无关    Rectangle rectangle = new Rectangle(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);}

再次运行程序,就能看到多了一个标题列,显示数据的行号!
