    Hi I have a question: how to assign QueryString value to a variable, that should return unique ID of a user from ASPDBNET table. I used wrote this way: string id=Request.QueryString["UserID"]; but it doesn't assigns any value... :( Thank u

                        It gives error becoz ur quiry string is null. check condition first if(Request.QueryString["id"]!=null) { code here } Best Regard Pathan
