Hi friends,
I have aspx page(uses master page), which has two iFrame
1. it contains dropdown list to filter the data
2. it holds the data to be displayed

My problem is, in 1st iFrame through javascript I'm setting 2nd iFrame src depending upon the dropdown value selected. 2nd iFrame src URL contains parameter in the query string

eq. wf_PrjEstDetails.aspx?id=0"

but when I try to access the parameter in the querystring in the wf_PrjEstDetails.aspx page using Request.QueryString["id"], it gives me null value.

Can you please tell me how i can pass and access the parameter in the querystring ?

This is my JavaScript Method:

JavaScript

function openWinSPV(strPath, object,objname)
{
   var selectedText = window.parent.frames(0).window.document.getElementById('ddlAccount').selectedIndex;
   var drpacc = window.parent.frames(0).window.document.getElementById('ddlAccount').options[selectedText].text;
   if(drpacc.indexOf("Select")!=-1)
   {
      alert('Please select an account!!!');
      return false;
   }

   selectedText = window.parent.frames(0).window.document.getElementById('ddlContract').selectedIndex;
   var drpcontract = window.parent.frames(0).window.document.getElementById('ddlContract').options[selectedText].text;
   if(drpcontract=="" ||drpcontract.indexOf("Select")!=-1)
   {
      alert('Please select the Contract!!!');
      return false;
   }
   selectedText = window.parent.frames(0).window.document.getElementById('ddlAccount').selectedIndex;
   //var arg= window.parent.frames(0).window.document.getElementById('ddlAccount').value;
   var arg= window.parent.frames(0).window.document.getElementById('ddlAccount').value;
   //alert(arg);
   strPath+="&id1="+ arg;
   arg= window.parent.frames(0).window.document.getElementById('ddlContract').value;
   //alert(arg);
   strPath+="&id2="+ arg;
   //if(window.parent.frames(0).window.document.getElementById('hdGrpCtr').value>0)
   
   if(window.parent.frames(0).window.document.getElementById('lblGrName')!= null)
   {  arg= window.parent.frames(0).window.document.getElementById('ddlGroup').value;
      //alert(arg);
      strPath+="&id3="+ arg;
   }
   else
   {       
      strPath+="&id3=0";
      arg=window.parent.frames(0).window.document.getElementById('ddlEstimate').value;
      strPath+="&id4="+ arg;
      strPath = strPath + "&random='" + Math.random() + "'"; //Added for call ID - 94483 to avoid caching of pages
      alert(strPath);
      window.parent.frames(2).document.location.href = strPath;
      //var newWindow=window.open(strPath,object);
      //newWindow.focus();
    }

I have written jquery method in wf_PrjEstDetails.aspx page

JavaScript

$(document).ready(function () {
                var qs = window.location.toString(); //.split("?")[1];
                //qs = qs.replace("id=", "");
                alert(qs);
                //                return qs;
            });

It gives some URL with encrypted parameters, is this reason in code behind it is not able to find id in QueryString??

Any idea??

Thanks in advance

<% Int64 ss =Convert.ToInt64( Request.QueryString["id"].ToString());%>
                       <% string bb = ss.ToString().Insert(0, "testing.aspx?id="); %>
