hi all,
       I am facing a problem that when i am opening a new webpage on the existing webpage then the value of session variable is not accessable in new opening page.it shows null.if i simple redirect the form by Response.Redirect then value is not loose.please help me

Whenever a browser application started a new sesssion is created.But a session is maintained if u navigate from one page to other. So make sure u'r code is just opening new pages.

Response.Redirect points away from your site and back into it. The server will think its a new user and will give you a new session.

Try using Server.Transfer if you are doing it internally.

That is not true. Assuming that you have session maintenance configured, any new request to the browser, whether it comes from a user click action on an <a> tag or from a Response.Redirect, will carry with it session identification in the form of the session ID in the cookie that is sent with each request.
