Default2.aspx

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>

<script type="text/javascript">
function Loadpage(lnk) {
try {
//reload page using new page size
var url = document.URL;
var index = lnk;
if (url.indexOf('Index') > 0) {
index = url.split('?')[1];
index = index.split('&')[0];
}
url = url.split('?')[0] + "?" + "Page=" + index;
window.location.href = url;
} catch (e) {
alert(e);
}
}
</script>

</head>
<body>
<form id="form1" runat="server">
<div>

<asp:LinkButton ID="lnk1" runat="server" Text="1" OnClientClick="javascript:Loadpage(1);return false;"></asp:LinkButton>
<asp:LinkButton ID="lnk2" runat="server" Text="2" OnClientClick="javascript:Loadpage(2);return false;"></asp:LinkButton>

<asp:LinkButton ID="lnk10" runat="server" Text="10" OnClientClick="javascript:Loadpage(10);return false;"></asp:LinkButton>

</div>
</form>
</body>
</html>

1) I am redirecting from Default.aspx page with querystring,It looks like this:

eg: http://localhost/Default2.aspx?CustomerId=1&ItemId=1

2)In Default2.aspx,I have buttons 1 to 10 (pasted above).

3)If i click on those button,it should attach to the querystring in the url:

eg: http://localhost/Default2.aspx?CustomerId=1&ItemId=1&Page=1

4) But now my issue is : if i click on 1st button - url changes to

eg: http://localhost/Default2.aspx?Page=1

5) i wanted the url like

http://localhost/Default2.aspx?CustomerId=1&ItemId=1&Page=1

and the page number should change based on the button clicked.

How to achieve this. Please help me with this.

Thanks in Advance.
