How to solve concurrent site issue


Hi All,

I have developed a ASP.NET2.0 web site with SQL 2000 backend and number users to site is approx. 5-10.

I have developed one Administration page which controls user roles to access this site; onclick of Update button in admin page the role gets updated into the system. I have written simple query in the code to update the user roles into database; Ajax implemented in admin page;

Issue: If 2-3 users tries to update the admin roles; latest update reflected in the database and same displayed in the admin page;

I am looking for a solution to solve this problem by application code change since i dont have flexible to change the database end; if one users update the system, it should not allow other users to perform any operation; please let me know if any standard approach can be implemented with minor code change.

Thanks in Advance,
