I'm currently developping a website using C# (ASP.NET framework 2.0).
On a page of the site there is a treeview ( 2.0 .Net component) on the
left from which you can open the details of nodes by clicking them. We
have a weird behaviour: sometimes when 2 users are accessing the site
simultaneously, a user gets the other user's data and vice versa.
Does someone have any idea whats's happening?
Thanks

Typically this is an incorrect usage of static (c#) or shared (VB) variables. They are shared by the whole application and ASP.NET runs as a single application. So if multiple users are hitting the site at the same time they'll work on the same data sometimes resulting in displaying other users data.
Do you have static or shared variable in the part that causes this problem ?

It seems you are using a shared object between user sessions. Do you use Application["..."] object to store current user data?

There is something about i didn't have take about : the problem is not systematic .It happen's perhaps one time in the day when there are 20 users using the web site.

no , i don't have Application["..."] object to store current user data but i use ViewState[""] to store user data .
No, the ViewState object is associated with the user Web page only. It is not because of this...

Can you give us the source code of the object that raises the problem. And another one that shows us how it is retreived.
Perhaps a singleton instance that manages shared objects?
Thanks.

Likely because it happens when two useds are hitting the site at the same time.
Knowing how you store the data that seems to be shared would be helpfull in finding out what goes wrong...
