Web Forms :: Make Validators Red Again In .net 4?
Jan 11, 2011
I recently upgraded my web app to .net 4 and was surprised to see that the validator controls are no longer red. People are calling up all confused because they can't see the error messages now.Any idea how to fix this in one go? I know I can do a kludge like forecolor=red on every single validator control, but that's ugly. I don't want to go back to <pages controlRenderingCompatabilityVersion="3.5" /> because it's time to move forward, but I do want validator controls people can actually see.

All ASP.Net client validation messages can be shown as an alert by setting the ShowMessageBox="True" property on the ValidationSummary control. This works fine for anything that happens on the client.
For the custom validators that validate server-side I had assumed that what would happen is that when the page is returned to the browser, ASP.Net would inject some javascript to show the alert box. However this isnt the case.
If you had relied on the message box to show detail and just have a * next to the erroneous field (as per my clients req's) then it wont work as intended. Does anyone have a solution for doing this? What I want is a way to possibly override the ValidationSummary control to inject javascript onto the page or something like this.

I have a page where I am using 2 update panels. The first update panel contains a form that has some validation tied to it. The second on has a simple form, but no validation. When I go to use the form in the second panel, the postback is halted by the validators in the first panel. Everything works as it should when I remove the validators.

I can't seem to get any sort of validator to fire when validating my DropDownList. I just want to make sure that it isn't left at "--Select--" when the user presses the Add button on the page. I've tried a range validator and required field validator and neither seem to fire at all. My DropDownList contains ID which is an int that is hidden and Name which is a string that is displayed. The ID is -1 for "--Select--". I use these all the time and can't understand why the page in this new solution is any different from other solutions I have done in the past. What have I missed?

I have a login web form with two textboxes for user name and pasword. The textboxes has a validator each and when I press the Login button everything is OK. I also have a second button which is used to redirect to a page for non logged in users. When I press that buon the form validators stops me from redirecting. How can I "use" validators for only one button and not the other?

Please correct me if I am wrong, or agree with me if I am right.
1. Validator.Enabled == false;
2. Before Page.Validate(groupName) is called, BaseValidator.Validate() is called.
3. If a Validator is not being displayed, such as being in an non active View of a MultiView.I even wrote a Custom Validator that was in View.It checked if Validator.IsValid and it returned true when it wasn't.Is there any way to get around number 3?

I have a webform that contains a few textboxes with required field validators and a gridview. I'm trying to add an edit function to the gridview, but when I go to update the textbox validators fire. Is there someway to trap the edit event and disable the rfvs? Will 'Mark As Answer' for replies leading to a solution.

I'm attempting to create a custom control that extends the Table class. Inside of the table will be rendered a number of different controls based on a specified identifying property. On some of these controls, however, I need to specify validation for data types and requirement. To me, the most logical way of doing so is to add validators to the table and set their appropriate properties to specify which controls to validate. In doing so, however, I've discovered that none of the validators added will even render on the page in which the control is added. So is this a valid construct?
Here's an example of what I mean:
[Code]....
End result? No validation. So what's the move?

I have a complex page with many validators on it. When I first hit the page, if I do a postback, all the validators fire off. If I enter like half of the textbox values and then try to go to the next page, it will stop me from going to the next page, but the red text errormessage does not show up. What am I doing wrong?
[code]....
In this instance, when I first hit the page, and try to go next, it will say: "Please enter Group Name."
If I fill in a few textboxes and then try to go next, it will not allow me to go next, but the text: "Please enter Group Name." does not show.

I have a contact page with fields like E-mail Address, Name, Subject, and Message. I use a RequiredFieldValidator on each text box. They work fine when I test it with the Visual Studio built-in development server, but on IIS7, they don't work and they allow the Send button's click event to be fired.

Is it possible to access a control's attributes within a custom validation method? Lets say I'm validating a textbox called txtName. Is it possible to access the ID of it or anything? args seems to only give me access to the value.

I have 2 date fields - From and To Date.Both are using required field validators, regular expression validtors and compare validators. When the user enters an invalid date range, e.g. 02-29-2010 to 02-29-2010 (non-leap year), the comparevalidator throws an 'from cannot be greater than to date range' error.Why am I seeing this error when From is not > To.Here's the code snippet

I will do my best to explain what I am trying to do. This is a form that will allow the user to change his/her password with RequiredValidators in place.Here's how to reproduce the problem that I can't seem to figure out.1. Please open up the aspx file into a browser.2. Click the "Save" button. The required validators should kick in and prompt a "Required" message.3. Key in any word in the "Change Password" textbox except for the word "pass" since I have hardcoded it into the aspx file just for example sake over here.
4. Key in anything for both the "New Password" and "Confirm New Password" textbox.5. Click the "Save" button again. You should be able to see "Your current password is incorrect." next to the "Current Password" textbox which is a Literal control.Here's the problem: How do I hide or get rid of the Literal control when I click save again? Right after the form does a post back, all the password textboxes are empty and I can't find a way to bypass the required validator controls and then screen would look like this below.I will attach my changePass.aspx file code below for reference.

what i want to do is to set up different validation summary for different type of validators. for example, for required field validators, if user leaves some required field blank, it shows that "You have to fill in mandantory information, indicated with a star"
and if some format is wrong, it shows that "format is invalid"
right now, i set all requied field validators' text to be a star, and leave error message to be blank. so that the validation summart will only display the header message. that is what i need. what i dont know is how to separate regular expression into another summary.
i think the validation group property requires multiple buttons. however, i only want one submit button, and this is where i got stuck.

The ValidationSummary panel shows up, even if the validator does not have an 'ErrorMessage'. When I click on Submit with invalid login, the error shows up in summary. That part's fine. When I submit with empty textboxes, it should show only the '*', but it also shows an empty summary panel. How can I prevent this. [Have a css class for .summary,header, summary ul, .summary ul li].
JS:
function validateTextBox(sender, args) {
var target = document.getElementById(sender.controltovalidate);
var is_valid = target.value != "";

I would like to find a way of running custom validation on a checkbox list. The reason why is because they were a radiobutton list. Then our client decided they wanted to be able to uncheck them (without a clear button) so in the end I had to change them to checkbox lists and make them mutually exclusive. On some of them, one must be selected and I downloaded this: [URL] to set them as required - worked nicely. Perhaps there's a way of building on this further to create some sort of custom checkbox validation. why I need this custom validation is because when the built form checkbox list = flat or maisonette then floor level is then required.

I have required field validators in my ASP.NET application form.
In the button click event of the FORM, i.e. OnClientClick(), I am calling a javascript function to validate the controls in this same page. Due to this the required field validators are not getting fired.
I need both the javascript function be fired on the button click , as well as required field validators also to work efficiently.

I am having an issue with a user control that contains a dropdown and a validator. I created a property for the "CausesValidation" property on the dropdown and set it to false. And yet the dropdown is still triggering the validator. I am having issues with this elsewhere as well including on my ModalPopup.

my problem is that i have a dynamic controls(text boxes) that are generated depending on a dropdownlist
and upon generating the textboxes i have created a required field validator and associated it to the text box that is being generated,
when javascript is enabled in my browser, the client side validation works fine, but when i disable the javascript.. no server side validation occurs and the Page.IsValid gives true when the method Page.validate() is fired
i tried a new simple page with dynamic controls and seems to work fine, but i could not figure out whats wrong with this page.
private void generateFarmForm()
{
int numberOfFields = 9;
Label[] labels = new Label[numberOfFields];
TextBox[] farmt = new TextBox[numberOfFields];
[Code]....
also the button that submits the form back has the same validation group,,, yet no luck with this... the page is in a content tag of a master page if this has any relation to the problem
