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：

后台代码

    
       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。

前台代码

    
      1<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" CellPadding="3" OnRowDeleting="GridView1_RowDeleting" OnRowEditing="GridView1_RowEditing"
