but if we delete the querystring part page should be redirected.

Hello Chandub,

There are a few ways of accomplishing what you are trying to do. I will give you one example.

product-detail.aspx

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="product-detail.aspx.vb" Inherits="product_detail" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
    <head runat="server">
        <title></title>
    </head>
    <body>
        <form id="form1" runat="server">
        </form>
    </body>
</html>

product-detail.aspx.vb

Partial Class product_detail
    Inherits System.Web.UI.Page

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        If (Request.QueryString("productid") = Nothing) Then
            Response.Redirect("product-detail.aspx")
        Else
            form1.InnerHtml = "Value in querystring is:" & Request.QueryString("productid").ToString
        End If
    End Sub
End Class

Happy Coding,

There Can be possibility of by default in product-detail.aspx page there would be something populated on the basis of productid.So plz check it .
