Validation - Pass Error Messages
Feb 3, 2010This is probably going to end up as a stupid question, but countless research has offered me no results. I know there are different types of errors I want to check for, and when I should be throwing an exception for "exceptional" errors, and that I should create validating functions for input and other checks. My problem is, how do I send an error back to a page when the data entered fails in a separate class?
For Example:
User input entered in Page1.aspx, click calls Submit() in Class.vb Class.vb finds that input is invalid How do I update Page1.aspx label to say "Hey, that is not right".
Bifurcating Validation Error Messages In .Net?
Jan 14, 2010In ASP.Net, how do I limit validation messages to only one?
Rule: User must put in a number between 0 and 1000.
Current [undesired] Behavior:
User types 1001: validator says "Please put in a non-negative number beneath 1000"
User types -1: validator says "Please put in a non-negative number beneath 1000"
Desired Behavior:
User types 1001: validator says "Please put in a number beneath 1000"
User types -1: validator says "Please put in a non-negative number"
In other words, how can I use two asp:RangeValidators whose disallowed values intersect but only turn on the desired one? I do not want to handle a ServerValidate event on the server.
MVC :: How To Customize The Generated (JavaScript) Validation Messages
Apr 8, 2010For example, if you use this attribute in a view model object:
[Required(ErrorMessage = "MyErrorMessage")]
public virtual string Subject { get; set; }
Then the following javascript will become generated (but below I have only copied the relevant part below) into the generated "mvcClientValidationMetadata": "Subject_validationMessage","ValidationRules":[{"ErrorMessage":"MyErrorMessage"
I know how it is possible to localize the messages in server validation, by adding your own localized message value to the ModelState, i.e. with the method 'ModelStateDictionary.AddModelError(key, "MyLocalizedMessage");' where the key can be retrieved as illustrated in the "GetErrors" method in the blog tutorial abot xVal [URL]
However, I have not figured out how to be able to customize the generated javascript, which I want to provide with the same localized validation messages as those that will become displayed when the server validation is executing (e.g. for clients that have disabled javascript).
MVC :: How To Disable ModelState Validation Messages (The Value '' Is Invalid.)
Mar 9, 2010I'd like to disable ModelState validation messages and keep my data annotation error messages.
When I update model, message "The value '' is invalid." apears in ModelState. I know that I'm trying to assign null to not nullable property, but I have my own validation and message.
I use something like this
[Required(ErrorMessage="Blahblah some error")]
I want user to see my message "Blahblah some error", but not stupid message: The value '' is invalid.
Web Forms :: Validation Error Messages Not Being Removed
Aug 5, 2010I have a form that has contact fields, billing address, and shipping address. So if i fill out my contact information ONLY and left billing and shipping address blank then hit submit, the validation for the billing address and shipping address appears. Ok no problem, there is a check in each billing and shipping fields that once click on it copies the address from contact to billing or shipping fields. Everything works except for the validation messages. They are still there. Is there a way to remove the validation message after the textboxes are populated with data?

View 4 RepliesMVC :: Can't Get Model Client Validation Messages Localized?
May 23, 2010i am currently working on an asp.net mvc (.net 3.5 sp1) web app, that uses data annotations and client side validation. I would like to have localization enabled, thus i have implemented a localization mechanism for enabling site visitors select the locale they prefer, by overriding the Execute() controller action and setting the CurrentCulture appropriately (i get the culture to change to from the URL route parameters).
I tried implementing my model validation messages localization with no success. What i did was adding two resource files undeer my model App_LocalResoorces folder (one for my locale greek language Validation.el.resx and one for the default english language Validation.el.resx) and set the appropriate file properties ("Access Modifier" to "Public", "Build Action" to "Embedded Resource","CustomTool" to "PublicResXFileCodeGenerator" and "Custom Tool Namespace" to "ModelLocalRes". Then i added a RequiredFieldPrompt" name-value to both the resource files.
Then i tried modify the required validation attribute on my model's name metadata like this:
[Code]....
The problem is that i cannot get the localization working, since the error message gets displayed always for the english default locale, no matter the locale selected from the site visitor.
MVC 2 Model Validation Messages - Turn Off / Customized?
Oct 19, 2010i 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)

Forms Data Controls :: Dynamic Error Messages For Validation
Mar 14, 2011I have the this current design. I use a web service/jquery perform client-side validation and to return 1 of 4 integers. At present I store it in a hidden field but it could be passed directly. I then deploy4 validators that when validated, validate the integer and trigger a custom error message. The ideal scenario I would like to be able to do this with one validator and switch the error message accordingly. On the server side the code could look like this:
[Code]....
As you can see my error messages are held as strings elsewhere which I reference for continuity throughout the project. unformtunately I don't know how to achieve this client-side by calling a javascript function. Sure I could hard code the messages in the javascript file as well, but this would mean that they were held in two places and suseptable to error. It may be an option to return an error message in the web service rather than an integer and trigger if it is blank.
Web Forms :: Validators Error Messages Not Showing In Validation Summary
Jul 28, 2010I have a validation summary (vs) and required field validator (rfv) on my page. The validation groups are not set in either of the controls. When I leave javascript on, the rfv fires correctly and the error message appears in the vs, as well as a * appearing next to the textbox I am validating. When I set the EnableClientScript=False for the rfv (forcing a postback and server side validate), the * appears, but the error message doe not appear in the vs. Why is the error not appearing in the vs? The fact that the * is appearing shows that the validator is being fired.

C# - How To By Pass Request Validation
Jan 2, 2011I have a GridView and I need update some data inserting HTML CODE; I would need this data been stored encoded and decoded on request.
I cannot in any way disable globally "Request Validation" and not even at Page Level, so I would need a solution to disable "Request Validation" at Control Level.
At the moment I am using a script which should Html.Encode every value being update, butt seems that "Request Validation" start its job before event RowUpdating, so I get the Error "Page A potentially dangerous Request.Form ... ".
void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
foreach (DictionaryEntry entry in e.NewValues)
{
e.NewValues[entry.Key] = Server.HtmlEncode(entry.Value.ToString());
}
