GridView动态绑定模板列值问题,急,救命

Question

数据表有一个列,ispass,值是1/0 
我加一个模板列button,如果是1的,button的test就是"已经审核",反之如果是0就是未审 
然后,我点这个按钮,点一次,未审变已审,已审变未审各位达人没时间定代码,请说一下方法和贴些关键代码出来
求代码,不感感激!!

Answer 1

Text='<%# Eval("ispass").ToString() == "1" ? "已经审核" : "未审核" %>

Answer 2

sbqcel(活死人):
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        string sID="";
        if (e.CommandName.Equals("IsPass"))
        {
            //GridViewRow row = GridView1.Rows[Convert.ToInt32(e.CommandArgument)];
            //sID = row.Cells[2].Text.ToString();
            Page.RegisterStartupScript("", "<script>alert('"+sID+"')</script>");
            //Student stu = new Student();
            //stu.StuId = sID;
            //int IsPass;
            //if(int.Parse(stu.StuIsPass)==1)
            //{
            //    IsPass=0;
            //}
            //else
            //{
            //    IsPass=1;
            //}
            //stu.StuIsPass = IsPass.ToString();
        }
    }我点这个按钮说是格式不对,该怎么写?

Answer 6

你使用了e.CommandArgument
但GridView的模板列Button 并未指定CommandArgument 所以取出的数据为空，转为int时失败<asp:Button ID="Button2" runat="server" CommandArgument='<%# Eval("id") %>' CommandName="IsPass" Text='<%# Eval("ispass").ToString() == "1" ? "已审" : "未审" %>'
 /> //指定CommandArgument值为id
 e.CommandArgument 就是获取当前点击按钮对应数据的ID

Answer 7

我按上面给的代码索引超出范围。必须为非负值并小于集合大小。
参数名: index 
说明: 执行当前 Web 请求期间，出现未处理的异常。请检查堆栈跟踪信息，以了解有关该错误以及代码中导致错误的出处的详细信息。 异常详细信息: System.ArgumentOutOfRangeException: 索引超出范围。必须为非负值并小于集合大小。
参数名: index源错误: 
行 37:         if (e.CommandName.Equals("IsPass"))
行 38:         {
行 39:             GridViewRow row = GridView1.Rows[Convert.ToInt32(e.CommandArgument)];
行 40:             sID = row.Cells[1].Text.ToString();
行 41:             //    //Student stu = new Student();
