Move the code from the page into a general DLL file - add a class called GeneralUtilities in your App_Code folder, and put the method in there as a static method. You can then access it from both pages.

"???"

Add a class to app_code.
Call it "GeneralUtilities.cs"
Include your method in this class as a static method:

C#

using System;
using System.Data;
using System.Configuration;
using System.Data.SqlClient;

public static class GeneralUtilities
    {
    public static MyReturnValue Less(MyParameterType myParam)
        {
        ...
        }
    }

You can then access it in both pages.

Solution 2

In QueryString you can pass like Response.Redirect("ProductCatalog.aspx?ID="+proid + "&less=true");

On target page Load Event

If(Request.QueryString["less"] !=null)
{
if(Convert.ToBoolean(Request.QueryString["less"]))
{
less();
}
else
{
more();
}
}

Hope this will help :)

Thanks
