Netscape required field validation problems

I have an interesting problem when I run the following
code in Netscape (7.02) vs. IE. This page works great in
IE and all my controls bring up the validation summary
dialog box if the required field is not filled out.
However in Netscape NONE of the required field
validations occurs at all in Netscape. The form is
posting correctly because I can walk through the post
back process. Any ideas why this is happening or how to
fix it?

Thanks in advance...

Hi,

if you mean client-side validation, that works only on IE by default. Other
browsers need to utilize server-side validation, that occurs automatically
as well, but you need to check Page.IsValid (or if specific validator then
it's IsValid) before critical code that relies on the validation runs. In
this case in the postback event, before any other code runs, check
Page.IsValid and if it's True then let the code run.

There are also so called DOM-compliant validation controls out there that do
the validation on client-side for every DOM-compliant browser.. If you
absolutely need such functionality, look for such controls.

Validate using IsValid() on the Server side. You should always do this, even
when client side is working, as one common hack attack is to create your own
form to by pass client side validation.

Not sure on NetScape 7.0. I know many browsers do not support client side
validation in .NET. NS has done some strange garbage with the 7.x version of
their browser, which breaks a lot of code.

The responses by Teemu and Cowboy never mentioned calling Page.Validate()
before checking Page.IsValid. I had thought that you needed to always call
Validate() before IsValid on the server side, but in re-reading the docs, it
does not appear that way, but can you explain when/what situations
Validate() is required to be called?

Thanks,
Chris

Cowboy (Gregory A. Beamer) said:
Validate using IsValid() on the Server side. You should always do this, even
when client side is working, as one common hack attack is to create your own
form to by pass client side validation.

Not sure on NetScape 7.0. I know many browsers do not support client side
validation in .NET. NS has done some strange garbage with the 7.x version of
their browser, which breaks a lot of code.

I have an interesting problem when I run the following
code in Netscape (7.02) vs. IE. This page works great in
IE and all my controls bring up the validation summary
dialog box if the required field is not filled out.
However in Netscape NONE of the required field
validations occurs at all in Netscape. The form is
posting correctly because I can walk through the post
back process. Any ideas why this is happening or how to
fix it?

Thanks in advance...
