Repeater和Datalist两层嵌套，如何在第二层取第一层的值？

Answer 1

好像是 Repeater rp = (Repeater)sender;

Answer 2

参考影片：http://download.csdn.net/source/332128

Answer 3

e.Item.DataItem
//example TypeInfo type = (TypeInfo)e.Item.DataItem;

Answer 4

op.QuestionRowId   =   int.Parse(drv["quRowid"].ToString()); 
                        dlq.DataSource   =   op.Select(); 
你反向查找一下drv["quRowid"] 它应该是唯一的吧~ 
你不是根据它来动态绑顶DataList的么, 在DataList的ItemDataBound中找到当前drv["quRowid"]
然后根据当前drv["quRowid"] 上Repeater 的数据源中查找想要的不赞同你的绑顶方式~

Answer 5

在 ondataitem 的 bind 事件中 通过 parent 获取上级（父）控件 要通过循环来获取，直到获取到 Repeater
也可以通过  label 等来传值

Answer 6

已解决,请看下面:protected void dlsel_ItemDataBound(object sender, DataListItemEventArgs e)
    {
        HtmlTableCell tdsel, tdfill;
        CheckBox chksel;
        RadioButton rdsel;        RepeaterItem rpitem;        
        DataRowView drv,drvrp;
        if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
        {
            rpitem = (RepeaterItem)(((DataList)sender).NamingContainer);
            drvrp = (DataRowView)rpitem.DataItem;                        chksel = (CheckBox)e.Item.FindControl("chksel");
            rdsel = (RadioButton)e.Item.FindControl("rdsel");
            if (bool.Parse(drvrp["radiocheckbox"].ToString()))  ====> 这个drvrp是repeater已绑定的值
            {
                chksel.Visible = true;
            }
            else
                rdsel.Visible = true;            tdsel = (HtmlTableCell)e.Item.FindControl("td1");
            tdfill = (HtmlTableCell)e.Item.FindControl("td2");
            drv = (DataRowView)e.Item.DataItem;
            if (bool.Parse(drv["isfillin"].ToString()))
            {
                tdsel.Visible = false;
                tdfill.Visible = true;
            }
            else
            {
                tdsel.Visible = true;
                tdfill.Visible = false;
            }
        }
    }
=========> to Sandy945 : [quRowid]字段是唯一的,但repeater已经绑定了需要值，没必要再根据[quRowid]
查询数据库得到所要的值，不过谢谢啦。
