Hi,

you can use ajax update panel to avoid page reloads.Yes those buttons generally loads entire page.

Best way to go with ajax.

I have tried Ajax Update Panel but Page Reload Problem remains same.
Though I can manage using Session in IF Condition BUT Page Postback creates unnecessary overhead to server. performance decrease and user experience decreases.
Could u please advise any other Reporting Tool to use on Web Pages.
Thanks.

ohk..just for testing purpose try this add your code in OnPreRender() method.

protected override void OnPreRender(EventArgs e)
{ }

and comment it in from preInit. Dont use ajax and all.

Problem remains same (page reloading) when i put my code inside
protected override void OnPreRender(EventArgs e)
{ }
