GridView实现自动编号

9.GridView实现自动编号：

效果图：

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：

 1protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
 2{
 3    //如果是绑定数据行 //清清月儿http://blog.csdn.net/21aspnet 
 4    if (e.Row.RowType == DataControlRowType.DataRow)
 5    {
 6        /**/////鼠标经过时，行背景色变 
 7        //e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='#E6F5FA'");
 8        /**/////鼠标移出时，行背景色变 
 9        //e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor='#FFFFFF'");
10        /**/////当有编辑列时，避免出错，要加的RowState判断 
11        //if (e.Row.RowState == DataControlRowState.Normal || e.Row.RowState == DataControlRowState.Alternate)
12        //{
13        //    ((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?')");
14        //}
15    }
16    if (e.Row.RowIndex != -1)
17    {
18        int id = e.Row.RowIndex + 1;
19        e.Row.Cells[0].Text = id.ToString();
20    }
21}

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。

1<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" CellPadding="3" OnRowDeleting="GridView1_RowDeleting" OnRowEditing="GridView1_RowEditing"
 2    OnRowUpdating="GridView1_RowUpdating" OnRowCancelingEdit="GridView1_RowCancelingEdit" BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px" Font-Size="12px" OnRowDataBound="GridView1_RowDataBound">

 4    <Columns>
 5        <asp:BoundField DataField="身份证号码" HeaderText="编号" ReadOnly="True" />
 6        <asp:BoundField DataField="姓名" HeaderText="用户姓名" />
 7        <asp:BoundField DataField="员工性别" HeaderText="性别" />
