Rick,
Which approach did you try? If you are posting back to the same page to perform the validation then you will have the data that was entered by the client. If the validation fails you need to set the corresponding form input values with the data.

>>Typically in the past I designed my pages to post back to themselves when server side page validation was required. If the validation passed I issued a server transfer to the next page. If it failed the page was sent back to the client with the submitted data filled in plus any validation error messages. This is also a typical approach used in ASP.NET.
