Recently I was looking at a set of 3rd party controls. One of these controls turned the background of a textbox red when a required field validation failed and then turned the background back to its original color when validation succeeded.I would like to add similar functionality to when using the asp.net 2.0 controls, but I have no idea how this was accomplished.
View 2 RepliesI have always been able to turn off request validation on IIS and cassini when I need to post HTML from an HTML Editor. Problem is I can't seem to do so on IIS express. Have tried the following:
<%@ Page Language="C#" ValidateRequest="false"
<system.web>
<pages validateRequest="false">
I have a wizard style MVC 2.0 application, when I move forward I want client side validation to kick in and validate the form, but when I hit the back button I want the data entered by the user posted back to the server so I can save what they have entered, but without any client validation.
View 4 Repliesi have a view model with a property like this one :
[RegularExpression(@"^d+$", ErrorMessageResourceType = typeof(Resources.Validation), ErrorMessageResourceName = "NumberValidationMsg" )]
public int? Number {get; set;}
NumberValidationMsg resource is set to "Only numbers allowed !".
but when I try to enter something like 'test' into Number field on form, ModelState displays the ErrorMessage with content similar to :
"The value 'test' is not valid for Number."
can this message be turned off, customized? (or maybe the best solution would be just to replace int? with string)
I've got an ASP.NET 4 site on which I want to allow people to put '<' in their password. However, .NET gets in the way by blocking (what it sees as) an attempt to put HTML in a form field. I know I can turn off input validation entirely, but I only want to turn it off for this one field. Does anyone know an easy way to do that?
View 2 RepliesI have the following object:

In my edit View, I have the following:

Lastly, my validation in my controller looks like this:
[Code]....
The validation works for both First and Last in that the Validation Message is properly displayed for the appropriate error. However, the input-validation-error class is not being set on the textbox.
How do I ensure that the input-validation-error class gets set on the textbox when the textbox is tied to a field in a nested class of the Model?
i have difficulty to show the validation error message next to textbox. fyi, the error message by default are showing in validation summary.
how to configure the validation error message in order to show next to (on right) a textbox. eg. in index.aspx or edit.aspx.
I have some code where I need two separate required field validators for one control, both in separate validation groups which are then validated by two separate buttons.This approach works well when the buttons are clicked but both validators show if I enter a value in the textbox and then remove it.
Is there a way to turn this"lost focus" validation off? I only need it to validate when the buttons are clicked.
EDIT,Unfortunately, if I set EnableClientScript=false then I dont have any client notifications. What I want is for the dynamic error message to show (effectivly in the OnClientClick event of the button) but not the "lost focus" of the textbox.Is there some way I can disable or "unhook" the lostfocus client event?
EDIT,A combination dDejan's answer and womp's answeer here sorted the problem perfectly.
My final code looks like this (for anyone else with a similar situation)...
Javascript...
<script type="text/javascript">
$(document).ready(function() { [code]....
So, now there is no validation until a user clicks either the "Get Email Confirmation Code" button or the "Register" button. If they click the "Get Email Confirmation Code" button all of the controls validate apart from the textbox where the user is to input the email validation code and we only see one validator message.
If they click the "Register" Button then all of the controls validate and we only see one validation message.If either button is pressed, the user goes back, adds and then removes some text then we only see one validator. Before this change you used to see both messages saying the same thing.
We have a ASP .Net based web service setup and hosted on a IIS v6.0. We wish to turn on custom error and disable debug mode. I understand these can be accomplished by modifying the web.config and machine.config file. However, since web service does not have a UI...please let me know if the changes made to the config files will take into effect. The reason why we wish to do these changes is because, our external auditors have flagged these as a vulnerabiity.

View 1 RepliesjQuery validation is working fine on my machine, when i pushed it to test server it won't it's throwing some errors which is kind of surprising.These are the errors I am getting: $.validator is null or not an object...I've never gotten this error before and it throwing an error when I declared a variable like var isValid.I don't know what to do. I am doing the custom validation methods not in the document.ready(). Does this cause this error? I wonder because all jquery validations are passing and hitting the server side validations.

I'm using 3 text boxes for allowing user selecting different ranges. I want to perform below validations on three text boxes.
1.User should enter a value (i.e. a valid number,doesn't allow to enter zero,decimal numbers and negative numbers) in 1st text box.

3. 3rd text box value should be greater than 2nd text box.
I want to perform validations on client side only using JavaScript. If anything goes wrong I want to populate a message box.
I have TextBox1 (enabled = true) and TextBox2 (enabled = false) in my WebForm on loading. Both are validated by means of a RegularExpressionValidator.
How can I set TextBox2 enabled = true ONLY AFTER (!) the text inserted in TextBox1 has been validated and accepted as valid ?
Can this be done on client side exclusively or is some code behind absolutely necessary ?
I have a asp.net webpage with textboxes on it. I have a button that changes the color of the textbox when clicked. Is there a way to save what color it is for each record in the database? So one record might habve a grey textbox and the other record might be yellow depending on what they choose.
View 4 RepliesI'm new to ASP.net and I need a little help. Windows has lots of places where text boxes show a light gray info message on the background telling the user what they can enter in that box. The message disappears as soon as the user types something in the box. How can I do that, I'm using ASP and VB.

Is there a way to disable request validation on an action without having to add the line <httpRuntime requestValidationMode="2.0"/> to Web.config? I'm currently posting XML to a controller action and get the "A potentially dangerous Request.Form value..." error. Is disabling request validation the only way to get the post to work, or is there some way I can intercept and encode the value that contains XML between the view and the controller action?
