用detailsview显示gridview 选择的详细信息

帮我看一下有什么问题  目前是gridview 选择之后detailsview仍旧没有出现
前面还经常在删除时报错 或者说该字符串未被识别为有效的日期时间 有一个从索引 0 处开始的未知字 我定义的是datetime型

  1.   

    你贴这么多代码 。。想。。干嘛？通过URL(a标签) 传值 页面接收 通过接受值 查询绑定
      

  2.   

    你的GridView的DataKey有两个值，
    所以不能所见即所得地设置AccessDataSource2的SelectParameters,
    应该将一下前台代码删除，用后台代码来设置！
    应该删除的代码：
      <SelectParameters>
        <asp:ControlParameter ControlID="GridView1" Name="comment_user_name"   PropertyName="SelectedValue" Type="String" />
        <asp:ControlParameter ControlID="GridView1" Name="commet_submit_time" PropertyName="SelectedValue" />
      </SelectParameters>后台设置在GridView1的SelectedIndexChanged事件中：
        protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
        {
            AccessDataSource2.SelectParameters["comment_user_name"].DefaultValue = GridView1.SelectedDataKey.Values[0].ToString();
            AccessDataSource2.SelectParameters["commet_submit_time"].DefaultValue = GridView1.SelectedDataKey.Values[1].ToString();
        }
      

  3.   


    如上改了之后
    “GridView1_SelectedIndexChanged”不是“ASP.backstage_aspx”的成员。是什么问题？
      

  4.   

    GridView1_SelectedIndexChanged是按了选择按钮发生的事件！
    具体操作：
    点中GridVew,在事件中找到SelectedIndexChanged事件，双击之！
