在aspx文件中操作： <asp:Repeater ID="ConsultRepeater" runat="server" OnItemDataBound="ConsultRepeater_ItemDataBound">               <ItemTemplate>  <%# Eval("Ucontent")%>     </ItemTemplate>  </asp:Repeater> 1.在对应的cs文件中，获取每项的数据的方法：  protected void ConsultRepeater_ItemDataBound(object sender, RepeaterItemEventArgs e)    {        if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)        {            Panel replyPanel = e.Item.FindControl("ReplyPanel") as Panel;//找到里层的repeater对象               DataRowView drv = (DataRowView)e.Item.DataItem; //***             if (string.IsNullOrEmpty(drv["Response"].ToString()))             {                 replyPanel.Visible = false;             }             else                 replyPanel.Visible = true;        }    }   2.多个repeater的嵌套使用： <asp:Repeater ID="ProductRepeater" runat="server"             onitemdatabound="ProductRepeater_ItemDataBound">             <ItemTemplate>                 <li>                     <div class="img">                         <img src='Prod_Images/<%# Eval("Pro_Small_Image") %>' height="100" width="100" />                     </div>                     <div class="text">                         <div class="title">                             <a href='coupon.aspx?bigcategory=<%# Eval("Pro_Table")%>&proid=<%# Eval("Pro_ID")%>'>                                 <%# Eval("Pro_Name")%></a></div>                         <div>                                                               <asp:Repeater ID="ParamRepeater" runat="server">                                 <ItemTemplate>                                     <span><%# Eval("Name")%>: <%# Eval("Value")%></span>                                 </ItemTemplate>                                 <AlternatingItemTemplate>                                     <span class="bar">|</span><span><%# Eval("Name")%>: <%# Eval("Value")%></span>                                 </AlternatingItemTemplate>                                 </asp:Repeater>                         </div>                         <div class="footer">                             <a href='coupon.aspx?bigcategory=<%# Eval("Pro_Table")%>&proid=<%# Eval("Pro_ID")%>'>                                 <asp:Label ID="CityLabel" runat="server" Text=""></asp:Label>共有<span class="digit"><%# Eval("CouponNum")%></span>条优惠</a>                         </div>                     </div>                 </li>             </ItemTemplate>         </asp:Repeater> 对应的cs文件： protected void ProductRepeater_ItemDataBound(object sender, RepeaterItemEventArgs e)     {         //判断里层repeater处于外层repeater的哪个位置（ AlternatingItemTemplate，FooterTemplate，         //HeaderTemplate，，ItemTemplate，SeparatorTemplate）         if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)         {             Repeater rep = e.Item.FindControl("ParamRepeater") as Repeater;//找到里层的repeater对象             DataRowView rowv = (DataRowView)e.Item.DataItem;//找到分类Repeater关联的数据项             string str = Convert.ToString(rowv["Pro_Content"]); //获取填充子类的内容             rep.DataSource = Product.FillPara(str); //LiftQuestionCtr.GetSomeQuestionsByTypeid(typeid, 2);             rep.DataBind();         }         Label cityLable = e.Item.FindControl("CityLabel") as Label;         cityLable.Text  = CityDA.GetCurCity();     }
