GridView实现自动编号

实现方法：
双击GridView的OnRowDataBound事件；
在后台的GridView1_RowDataBound()方法添加代码，最后代码如下所示：
    protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        //QQ:272912705 光之翼 www.hi.baidu.com/jcomet       

if (e.Row.RowType == DataControlRowType.DataRow)
        {
            ////鼠标经过时，行背景色变
            //e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='#E6F5FA'");
            ////鼠标移出时，行背景色变
            //e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor='#FFFFFF'");

            ////当有编辑列时，避免出错，要加的RowState判断
            //if (e.Row.RowState == DataControlRowState.Normal || e.Row.RowState == DataControlRowState.Alternate)
            //{
            //    ((LinkButton)e.Row.Cells[6].Controls[0]).Attributes.Add("onclick", "javascript:return confirm('你确认要删除：\"" + e.Row.Cells[1].Text + "\"吗?')");
            //}

        }
        if (e.Row.RowIndex != -1)
        {
            int id = e.Row.RowIndex + 1;
            e.Row.Cells[0].Text = id.ToString();
        }

    }

 

注意这时最好把前台的第一列的表头该为“编号”，因为以前的第一列被“吃掉”了。
