Solution 1

Take the indexing out - Session contains the Abandon method, not the indicvidual items...

C#

void logout(Object Sender, EventArgs e)
    {
    FormsAuthentication.SignOut();
    Session.Abandon();
    Response.Redirect("index.aspx");
    }

If you read my answer, that is what I wrote last time...

but this code is not deactivate back button of index.aspx page.When i press back button of index page of explorer it is again going to previous page.

No - and it won't.
There is no way to disable the back button - and the page it goes to is held in a cache locally by the browser itself, rather than being loaded fresh from the internet.
There is a discussion on this here: but as he says, it doesn't necessarily work with all browsers!

but what about LogOut?

OriginalGriff 30-Dec-11 3:57am

That code does the log out - what are you asking about?

Session["Name"].Abandon();
This is WRONG.

'Session' object has 'Abandon' property exposed to it. Individual items do not. I am not sure how you were able to put Abandon after individual reference as Visual Studio would not suggest the same. Try to use the VS auto-intellegense and you will see by yourself what all are exposed and accessible.
