Form validation

I have a form with the usual Contact details on. I am using the required field validator to make sure that certain fields are entered before continuing. I am also using the validation summary to show which fields have not been entered.

Easy so far.

I have Work Tel, Home Tel and Mobile text boxes. I only require one contact number. How do I use the required field validaitor to check that at least one of these fields has been entered.

ASP.NET

You'll probably have the most luck using a CustomValidator instead of a RequiredFieldValidator. CustomValidators can use either client-side or server-side functions to validate. There's more info here: http://www.w3schools.com/aspnet/control_customvalidator.asp and here: http://www.dotnetjohn.com/articles.aspx?articleid=64

I almost have it.

The error only seems to show when i have cleared all the required field errors. Also the page does not scroll to to top in the same way ??

Are you validating client-side or server-side? As for scrolling, try putting MaintainScrollPositionOnPostback="true" in your Page declaration. (Doesn't always work for me, but every once in a while it does help. :) )

Hi

I have decided to write my validation code in my business object class instead. There will be no validation code in the form class. I think this is a much better way of doing it . I really dont like the validation controls anyway.

But you are right the custom validatior is the way to go. i understand the stuff about client and server stuff. But I really dont want any java script in my app if i can help it.
