Repeater 嵌套绑定数据

 

cs:

//repeater的databound事件
        protected void RptBig_ItemDataBound(object sender, RepeaterItemEventArgs e)
        {
            //此处必须做判断，不然下面获取数据会报没有实例化或者为空
            if (e.Item.ItemType== ListItemType.Item||e.Item.ItemType== ListItemType.AlternatingItem)
            {
              Repeater rptSmall=  e.Item.FindControl("Rptsmall") as Repeater;//找到嵌套的控件
            DataRowView ros=  (DataRowView) e.Item.DataItem;//获得相关联的数据项
            int id = Convert.ToInt32(ros["id"]);//获取对应行的Id
            DataSet ds = Small(id);//自定义方法查询
            rptSmall.DataSource = ds;
            rptSmall.DataBind();
            }
        }
