It will show the error messages provided you either have a ValidationSummary
control on the page or you have the Validation control's Display property
set to something other than "None".
Also, it is important that you not redirect from the page, and you will need
to make sure that you check whether the page is valid before performing any
operations, hence why I included the if (Page.IsValid) part of the code.
