Help with C#/SQL

Question

I have a webform that I am using to post data to a SQL database. I have been able to sucessfully submit data to the database however; where I am lacking in my application is either a panel or page that displays either the success or failure of the post. Ideally, I would like to have a panel that displays the data posted with a success message or another panel that displays the error and retry message. Can someone point me to a link or example on how to do this? Thank you for your time. Sincerely, Tim
