AJAX :: Requiredfieldvalidator Works But Does Not Show Error Message?
Feb 14, 2011
I placed 2 requiredfieldvalidators in my page (well, actually, more like a dozen of them, but only these 2 behave this way) and can not seem to figure out why the error message will not be displayed. The validation function works (the processing code is not run and focus is returned to the first field that fails validation) but no error message.

I have a textbox, with a RequiredFieldValidator and a ValidatorCalloutExtender. The calloutExtender comes up when there is no text in the textbox, but it does not display the error message from the RequiredFieldValidator. I tested this code in a test app, and it worked. It may have something to do with the content containers? These controls are inside of a web user control, which are inside a Telerik RadDock. The parent page also uses a MasterPage. Here is my code from the usercontrol which contains the validator:
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="WebUserControl1.ascx.cs" Inherits="WebApplication1.UserControls.WebUserControl1" %>
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit"

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).

I'm making a website in ASP.NET 4.0 where I make use of the RequiredFieldValidator control to validate a wizardstep.It works perfectly with Javascript enabled, but when I turn it off (in my Firefox) it just goes to the next step.We don't do a Page.IsValid check, but we don't do much on the "next button clicked" event either.Certainly not something that is forcing it to go to the next step.

I just tested a new aspx-website and in the debug mode it works fine.
But when I publish it on the server 2003 with IIS6 then it works first and after several requests I get an error message page not found.
The page itself exists and I think that it is only unavailable on the server.

Is there a way to have my errorpage show the actual error...if it occurs within my IP range? :)
Or perhaps if I'm in my IP Range, then don't show the custom error page, show the actual crash page...

I'm using the Authorize attribute to filter controller actions based on user roles, but if an unauthorized action is attempted, the user is redirected back to the login page. As I user I would find this confusing and irritating. How can I instead show an error message informing the user they need certain roles, and remain on the view where they attempted an action?

I'm using what I believe is a pretty common/boring/generic implementation of a ModalPopupExtender. I'm using client-side JS to show the dialog when the user clicks a link, and hide it if they click "cancel". I only do a postback if they truly want to save the data.
I can click the link to show the dialog, then click the cancel button to hide it, then click the link to show it... ad infinitum. If I decide to save the data via a postback, everything works well, and the dialog is hidden as a result of the postback, all as expected.
However, once the postback completes, my client-side JS show() never works again. Any attempts to click the link fail quietly; no error messages, the dialog just never shows again.

I have a datasource (which is a query) that could run more than 30 secs. I want to show to a user an animated icon (I have it already) while the Gridview is waiting to return data.
I studied several tutorials and textbooks but all just "thoerectically" use a timer to simulate, without much application to real example above. How should I code it in the above real scenario ? In which event handler to put the code and what control (Update panel) to use and any sample code ?
