ASP.Net Project having Problems URGENT

ASP.Net Visual Studio 2005 with C# coding web Application with back end MS SQL Server is having the follwoing problem. The Problem is some times some of the data is getting duplicated while saving. This does not happen always. And some times when editing the previously entered data and saving, some old data is getting deleted. Also sometimes data entered gets deleted. May be the problem is in the web page refreshing or session refreshing etc. Looking for an expert to look at the code through [login to view URL] (remote desktop) and provide a solution for this problem at concept level. This requirement is very urgent. If you are an expert then only reply. Thanks
