怎么获取repeater前台控件的值

Question

我在page_load里面获取的，但是获取的都为Null，请问怎么获取到我前台是这样写的 <asp:Repeater ID="Repeater1" runat="server">
        <ItemTemplate>
            <asp:Panel ID="plURL" runat="server">
              <iframe width="1020px" id="IFURL"  height="900px" frameborder="0" scrolling="no" src='<%#Eval("s_URL") %>'></iframe>
            </asp:Panel>
            <asp:Panel ID="plImage" runat="server"  Visible="false">
             <asp:Image ID="imgPic" width="1020px"  height="700px" ImageUrl='<%#Eval("S_picture") %>' runat="server" />
            </asp:Panel>
           
      <p></p>
       <a style="font-size:14px;">说明：<%#Eval("S_instruction") %></a>
        
        </ItemTemplate>
        </asp:Repeater>
现在我就想获取到panle，就是plurl和plImage

Answer 1

page_load 里怎么能获取呢  
Repeater1_ItemDataBound 事件Panel p = (Panel)e.Item.FindControl("Panel控件的ID");

Answer 2

获取前台的控件id不容易么？后面跟了runt=“server”就行

Answer 3

<asp:Repeater ID="repeater1" runat="server">
<ItemTemplate>
     <asp:Panel ID="plURL" runat="server">
              <iframe width="1020px" id="IFURL"  height="900px" frameborder="0" scrolling="no" src='<%#Eval("s_URL") %>'></iframe>
            </asp:Panel>
            <asp:HiddenField ID="hidden1" runat="server" Value='<%#Eval("s_URL") %>' />
            <asp:Panel ID="plImage" runat="server"  Visible="false">
             <asp:Image ID="imgPic" width="1020px"  height="700px" ImageUrl='<%#Eval("S_picture") %>' runat="server" />
            </asp:Panel>
           
      <p></p>
       <a style="font-size:14px;">说明：<%#Eval("S_instruction") %></a>
</ItemTemplate>
</asp:Repeater>
代码：
 for (int i = 0; i < repeater1.Items.Count; i++)
        {
            HiddenField hf1 = repeater1.Items[i].FindControl("hidden1") as HiddenField;
获取另一个同上。。
        }

Answer 4

Repeater1.DataSource = dt;
Repeater1.DataBind();
在绑定之后才能取，rowIndex是行号~
Panel plURL=(Panel)Repeater1.Controls[rowIndex].FindControl("plURL");
