We deployed our legacy ASP.NET application to production after successful test deployments to our staging environment. The application makes use of RequiredFieldValidators on one particular registration page. On our development and stage environments, the validators successfully detect empty fields when “Submit” is clicked, error messages are displayed, and form submission is prevented.

But on production, the validators do not display error messages. Clicking submit will cause a postback, the code-behind checks for Page.IsValid and correctly detects the form has missing fields, but the registration form is redisplayed with no error messages (ie “Please enter an email”) to the user.

Sample: (note I dont explicitly declare EnableClientScript or SetFocusOnError)

<asp:requiredfieldvalidator id=Requiredfieldvalidator1 runat="server" CssClass="NormalRed" Display="Dynamic" ErrorMessage="Please enter an email." ControlToValidate="txtEmail"></asp:requiredfieldvalidator>

Both environments (stage and production) are identical: Win2K3 Server and IIS 7, SQL Server 2008, and ASP.NET 1.1 runtime (embarrassingly).

Any ideas?

    Are the referenced aspnet_client folders the same or are you using different versions there?
