Asp.net 如何获得中继器中所有标签的总和？

我想得到转发器内所有lblAUSD的总和，但不知道如何得到它。请帮忙：）提前谢谢

是否有任何代码，我可以从中继器计算总和，我在Gridview中有我的代码，但不知道如何在中继器中进行计算

Gridview - This is the code behind from my GridView


Dim sum As Integer = 0
    For i As Integer = 0 To grvOperationalCost.Rows.Count - 1
        sum += Convert.ToDecimal(grvOperationalCost.Rows(i).Cells(2).Text)
    Next
    lblTotalCosts.Text = sum.ToString()

Repeater - This is the Item Template in my Repeater

<asp:Repeater ID="reptrData" runat="server" >
     <ItemTemplate>
         <div>
           <h6>Product Details</h6>
              <table style="width:100%">
                     <tr>
                         <td></td>
                         <td style="text-align :right">  <asp:Button ID="bttnViewPlattDetails" CommandName ="ViewPlatts" runat ="server" Text="View Platts"  /> &nbsp;<asp:Button ID="bttnRemove" runat ="server" Text="Remove" CommandName ="Remove" />
                         </td>
                     </tr>
                 </table>
             <asp:Panel ID="PanelHeader" runat="server" CssClass="ui-widget-header">

                 <table>
                     <tr>
                         <td><b>Product:</b></td> 
                         <td><asp:Label ID="lblProduct" runat ="server"><%#Eval("plCode")%></asp:Label><asp:Label Id="lblAProduct" runat ="server"  Text='<%#Eval("pHideCode")%>' visible="false" ></asp:Label>

                        </tr>
                     <tr>
                         <td><b>Date:</b></td>
                         <td><asp:Label ID="lblDate" runat ="server"><%#Eval("plDate")%></asp:Label><asp:Label id="lblDate1" runat ="server" CssClass="frmdate" visible="false" Text='<%#Eval("pHideDate2")%>'></asp:Label> <asp:Label ID="lblDate2" runat ="server" CssClass="frmdate" visible="false" Text='<%#Eval("pHideDate2")%>' ></asp:Label>

                     </tr>
                    <tr>
                        <td><b>Average:</b></td>
                        <td><asp:Label ID="lblAverage" runat ="server"><%#Eval("plAverage")%></asp:Label></td>
                    </tr>
                     <tr>
                         <td><b>Net Purchase Price:</b></td>
                         <td><asp:Label ID="lblNetPurPrice" runat ="server"><%#Eval("plPurPrice")%></asp:Label></td>
                     </tr>

                </table> 

                 <table style="width:100%">
                     <tr>
                         <td></td>

                     </tr>
                 </table>
            </asp:Panel> 

               <asp:GridView ID="grvPlatts" runat ="server"></asp:GridView>
              <hr />                            
    </ItemTemplate> 

Gridview-这是我的Gridview中的代码
点心作为整数=0
对于i作为整数=0到grvoOperationalCost.Rows.Count-1
sum+=Convert.ToDecimal（GRVOOperationalCost.Rows（i）.单元格（2）.文本）
下一个
lblTotalCosts.Text=sum.ToString（）
Repeater-这是我的Repeater中的项目模板
