multiple entries in sql database instead of one entry. (may be due to sessioning ?) in asp.net c# 4.0

Question

i have used sessions in my web app.
and i sets up sessions on login with userid.

sometimes when one user will post their problem using my web application.,
than entry will be there with that perticular userid and another entry also be there with any random userid.

so, multiple entries will be there in same table in sql. (this happens randomly)
(this happens - when 2-3 user trying to access same thing)

sometimes it takes any other / random userid (may be previously logged in user id) and insert data with any userid.

and

sometimes one user wants to see log of his activity
so he able to see another users activities or all users activities or his own activities . this one happens randomly too.

please help.

mail id is: [email protected]

static userid is causing the issue. so convert it to non static variable. I am using static class object for Session. this happens due to statics objects. so remove all static objects and working with some class and using objects.

Check following things if you have custom developed memberships i) expire the session on logout immediately ii) you need some unique value that identifies the form/page - perhaps a generated number in a hidden field - and remember/check that is has been processed iii) Disable the button after click iv) always use if (!IsPostBack) { //inserting procedures } Hope this helps.
