Question about Validation Controls

[Guest]

Hi,

I have a form with three text fields and a Submit button. The two text
fields have ReqiredFieldValidator and third text field has
RegularExpressionValidator. The page validation works fine in Internet
Explorer but I noticed that in FireFox, Netscape and Mozilla, they don’t
work.

These validation controls are set to run servside then why they don’t work
in non-IE browser.

Is there any workaround?

Thanks,

Joe

Tt work in non-IE browser.

Did you implement the server side event handler for the validation
controls?

in the code behind in onload check Page.IsValid. referencing this property
run the serverside validation routines.

In VS.NET, you don't need to do anything to implement the server-side events
(unless you are using a Custom Validator).

Just incase the guy was using a custom validator.

In anycase, to the OP - did you call Page.Validate?

Hi Joe,

Let's get back to your original question. Yes, there is a way to get
client-side validation to work with non-IE browsers. ASP.NET 2.0 and my
Professional Validation And More (http://www.peterblum.com/vam/home.aspx)
are two solutions. For details on this issue and much more knowledge about
the Microsoft validators, see this article: www.aspalliance.com/699.

I also noticed that in your code, your ValidationSummary control has
ShowMessageBox=true and ShowSummary=false. The ShowMessageBox feature
requires client-side validation. On non-IE browsers, the ASP.NET 1.x
validators simply will not show anything for the ValidationSummary. So if
you want this to work, you will have to consider the alternatives (my
software, other third party controls, or ASP.NET 2.0).

Thanks guys, I noticed that I wasn’t using Page.IsValid and then if the empty
form is submitted then I user can’t submit the form but because I am using
ShowMessageBox="True" ShowSummary="False" to display an alert pop-up window
in IE, how do I show a message to user in non-IE on postback?

Any clues and thanks for your great help.
