Question

i have a web form in which i created multiple textboxes base on user requirement

 <table  id="tbl1"  class="form-group">         
    <tr><td class="col-sm-1">Code:</td><td >
<asp:TextBox OnTextChanged="txtCode_TextChanged" AutoPostBack="true"  
runat="server" ID="txtCode"></asp:TextBox></td>

runat="server" ID="txtFine"></asp:TextBox></td> 
<td> <a href="java<!-- no -->script:void(0);" id='anc_add' class="btn btn-green">Add Code</a></td>     
   <td><a href="java<!-- no -->script:void(0);" id='anc_rem' class="btn btn-red ">Remove Code</a></td></tr>
 </table>         <script>             $(document).ready(function () {      
           var cnt = 2;                 var cnt1 = 2;   
                $("#anc_add").click(function () {      
               $('#tbl1 tr').last().after('<tr><td class="col-sm-1"> 
Code:' + cnt + '</td><td  class="col-sm-1"><asp:TextBox  runat="server" ID= "cnt"  >
</asp:TextBox><td class="col-sm-1"> Fine:' + cnt1 + '</td>
<td  class="col-sm-1"><asp:TextBox  runat="server" ID= "cnt1"  >
</asp:TextBox></td></tr>');        
             cnt++;     
                cnt1++;   
              });      
             $("#anc_rem").click(function () { 
                    if ($('#tbl1 tr').size() > 1) {   
                      $('#tbl1 tr:last-child').remove();    
                 }            
         else {      
                   alert('One row should be present in table');
 }                 });    
             var getval = $('input[data-type="number"]').val;  
           });  </script>   

there may be 2 or three rows with 4 or 6 textboxes,
i want to store these values in session ,and then call session in code behind ,and insert into database using for loop??does there is any solution?
