Hello Nagendra,

I suggest that you try using the code for the page size inside "(!Page.IsPostBack") of the Page_Load event and see if it makes any difference.

Additionally, if the problem persists I will ask you to open a formal support ticket and send us some test project we can debug locally.

Greetings,
Pavlina
