Solution in C# which you can understand and translate later...

Instead of Session, you can use a static variable like:

static int recordPerPage = 20;

Then, in Page_Load():

if(Request.QueryString["Page"]!=null)
{
   if(Request.QueryString["Page"].ToString()=="2")
       recordPerPage = 150;
}

Above mentioned is the main and correct solution for your problem according to me. Still, if you want to clear the Session variable, you can do it easily by:

Session["recordPerPage"] = "";

You have to do this as Session variables do not lose their values on another Page call / Load. This is their main property and that's why they are used. And if you want to clear their value, you have to clear it manually by assigning null or "" value to them.

Solution 1

First of all, I am not sure why are using Session to store the Page length. It should be an application/page setting instead. On one page set it 20 and 150 on another, that it!

Solution 3

There is no need to store record count in Session, you can directly get it by using GridView's object.
if you want to clear session value then you can use following code

Session("recordPerPage") = ""

In your code you have use the same veriable in Application object also, why so ?
