Try changing this line:

ListBox1.DataSource = users;

To this:

ListBox1.DataSource = onlineUsers;

Also do not forget to set the DataKeyField and DataValueField properties on the ListBox1.

Thanks Funny mistake!! it works, but it shows me some offline users!! that's strange! – Jan 08 '13 at 12:33
No problem, glad to help - the "offline" users issue might be session timeout related - i.e. even though the user has closed the browser the session has not yet timed out and therefore is still showing them as "online". Oh don't forget to mark this question as complete (and vote up my answer if you are able!). – Luke Baughan Jan 08 '13 at 12:47
How can can i remove this problem. Do you have any idea? – Jan 08 '13 at 13:37
AFAIK there is no "clean" way to do this - search stack for "ASP.NET Force logout" and you'll get a mix of results some of which might be suitable. – Luke Baughan Jan 08 '13 at 14:10
