    you have to use

    <div>
   <form action="#" method="post" >
      
    <asp:ScriptManager ID="ScriptManager1" runat="server" />
  <asp:UpdatePanel ID="UpdatePanel3" runat="server">
 ...
 <asp:TextBox ID="txtEmail" runat="server" CssClass="form-control"</asp:TextBox>
....
    </form>

    and get value

    var email = txtEmail.Text;
