会话值存储在两列而不是一列中

Question

我遇到以下代码的问题。当我点击Repsendbtn时，它会将UsrNme的相同会话值存储到Receiver和Sender列，其中应将会话值保存到Receiver并导入{{ 1}} Sender

的值

tolbl

代码：

<asp:FormView ID="repmsgform" runat="server"  DataKeyNames="mailno" Width="100%" >
    <ItemTemplate>
        <div class="col-lg-12"> 
            <form class="well span8">
               <div class="row">
                   <div class="span3">
                      <label>From</label> 
                      <asp:Label ID="tolbl" runat="server" CssClass="form-control" Text='<%# Bind("Receiver") %>'></asp:Label>
