Basic validation on an ASP.net page
Posted on 2003-03-19
I have a ASP.net page that offers the user 3 radio buttons. Alongside each radio button is a list box of values. The idea is that the user may select a radio button choice (they are mutually exclusive). Having selected a radio button, they MUST then select a value from the corresponding list box - they should not be allowed to select the radio button and then not select a value from the list box that's alongside.
How can I put validation in place to ensure this happens ?
I'm using VB.net as the code behind language.
