<p style=" <strong style="font-weight:bold; font-style:inherit; font-family:inherit; outline-width:0px; outline-style:initial; outline-color:initial; padding:0px; margin:0px; border:0px initial initial Im still new to C# and Ive been working with my Validator
lately.
<p style=" <strong style="font-weight:bold; font-style:inherit; font-family:inherit; outline-width:0px; outline-style:initial; outline-color:initial; padding:0px; margin:0px; border:0px initial initial I have a program right now that generates a form on Microsoft
Visual Studio 2010. The form needs the user to type in First, Middle, and Last Name. Also Email.
<p style=" <strong style="font-weight:bold; font-style:inherit; font-family:inherit; outline-width:0px; outline-style:initial; outline-color:initial; padding:0px; margin:0px; border:0px initial initial What I want my Validator to do is be able to detect if
the user left anything blank. If so I want a message to display saying.. "ERROR: First Name is blank" something like that.
<p style=" <strong style="font-weight:bold; font-style:inherit; font-family:inherit; outline-width:0px; outline-style:initial; outline-color:initial; padding:0px; margin:0px; border:0px initial initial Also I want my Validator to be able to know if the Email
address entered is a Valid Email Address. If not I want "ERROR: Email address is not valid" to be displayed. Appreciate any help. Thanks. I will post my code for my form and my validator.
