Ramasububbu:
This is not the right forum at p2p.wrox.com for this question. This should go in one of the technical forums, perhaps one of the ASP or (ASP.NET) (http://p2p.wrox.com/asp-net-asp-12) forums if you are using these components in ASP.NET pages. I see several related OWC questions and answers in those forums already. If you'll repost you question in one of the appropriates forum along with more information about what you're using OWC with, you'll probably get better help. This particular forum is for questions about this site itself.
