Html.ValidationSummary Showing Duplicate Error Messages
Nov 30, 2010
I have searched and Googled for the answer to this question to no avail. I'm using EF4 and ASP.NET MVC2 and I have an EF4 entity "Award" with a non-nullable string field, "RecipientID". I'm using DataAnnotations for server-side validation, so in my "Award" partial class I've set up the RecipientID to have the Required attribute. When I try to submit the form with the RecipientID text box empty, I see my error message "Please enter a recipient" in the Html.ValidationSummary twice.
Would this be because the error is being thrown both by the entity (in that it is a non-nullable field with a null value), as well as the application? Whatever the reason, is there a way to "fix" this and have the error message show up only once? (Fix being in quotations because I'm not sure if this is intended behavior or not.) I didn't think it would be necessary to include relevant code, but I will if it's needed.

I 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.

I've placed Html.ValidationSummary(true) on my page so that an error can be displayed that are not associated with a field.
This renders the following html <div class="validation-summary-errors"><ul><li style="display: none;"></li> when there are some ModelState errors are present, all of which are associated with a field. ie there are no page level errors
I've put some background and border styles on the div which give the look that I want.
The problem is that the div is visible even though the collection is empty.
I understand why this is happening but was wonder if there where any techniches to prevent the html from being rendered or to hide the div using styles if the ModelState errors collection is empty?
If its possible I'd like to avoid using jquery to hide the validation summary as the site should work without javascript.

I have to customize a validation scheme for my form because required validation is only necessary if 2 other conditions are met; I have this figured out, but is there a way to add the messages to the ValidationSummary Control using C#

How is it possible to add a custom error message to the ValidationSummary HtmlHelper? Can it be part of my model? It's for a sign up form and I need to validate whether the user already exists.

When my validation fires on my web form, the validation summary writes out the same error message for each control that was in error
twice! I have no validation groups in my web form.Here is my html for the Validationsummary control.
<code>
<asp:ValidationSummary ID="ValidationSummary1" runat="server" DisplayMode="BulletList"
ShowMessageBox="true" ShowSummary="false" EnableClientScript="true" HeaderText="You must enter a value in the following fields:" />
</code>
A typical control is set up below as follows:
<code>
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" ControlToValidate="HospAcctno"
ErrorMessage="Patient Info: Hosp Acct#" Text="*" runat="server" />
</code>

For error messages, validation faults etc you have
ModelState.AddErrorMessage("Fool!");
But, where do you put success responses like "You successfully transfered alot of money to your ex." + "Your balance is now zero". I still want to set it at the controller level and preferably in key-value way, the same way as errormessages but without invalidating the modelstate.

I'm trying to add a new html attribute to my ValidationSummary Html control like this:
<%= Html.ValidationSummary(new { id = "validationSummary" })%>
VS compiler has no problem with it, however when it comes to running it in the browser I get the nasty error message saying:
'System.Web.Mvc.HtmlHelper<Adgistics.Mvc.ViewModels.Forum.IForumCreateOutModel>' does not contain a definition for 'ValidationSummary' and the best extension method overload 'System.Web.Mvc.Html.ValidationExtensions.ValidationSummary(System.Web.Mvc.HtmlHelper, string)' has some invalid arguments

I am trying to make an AJAX Form work correctly with Client Validation, but I can't seem to figure out how to make it work together.Currently I have a view like this:
[Code]....
My model:
[Code]....
The client validation works on the Required and Stringlength attributes, but if I put an incorrectly formatted email, it still returns successful. Is there a special way to do the regular expression attribute? Or am I doing it wrong?

I am not sure what I am doing wrong in how I set up validation on my models and viewmodels. For some reason on several of my views that contain a validation summary, it appears empty on initial load of the page. On some other pages it appears correctly when the form's data is posted and it does not appear on initial load, this is the way that I would expect it to work.
On the views where this is occuring, my viewmodels are somewhat more complex in that they contain another complex type that I am passing around that has it's own set of DataAnnotation Validation properties, but I have called the validation summary like this; Html.ValidationSummary(true) so that those properties are not validated.

I'm using emails as the user name, and I've got requiresUniqueEmail="true" in the web.config.
I have an empty CreatingUser method, and in CreatedUser I perform a couple of table entries with the new user.
When I try to add a user with an email that's already in use, I get a the default success message. But no user is added, and
it doesn't reach the CreatedUser method.

I am creating a web form that requires a lot of validation. I use many of the validation control in asp.net already like RequiredFieldValidator and CompareValidator.
My Problem: after my custom validation for the value entered return an error message, and I pressed enter key when the field is empty, my custom error message is overlapped by my ValidationSummary.
Setting my custom error to visible = false on button click also does not seem to work as it requires for me to enter the value first.
This made me think, is there a way to insert my custom validation inside the ValidationSummary as an error message like for other validation control?

This 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".

In 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.

I 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?

I'm running Visual Studio 2010 and IE9 and integrating with facebook and the facebook javascript code keeps resulting in exceptions... 'Error: '__flash__removeCallback' is undefined' which I can't do anything about.
Visual Studio keeps on telling me about each and every one of these exceptions every time I load the webpage that I'm working on which makes doing anything else difficult. I managed to switch off this behavior by enabling Silverlight debugging because apparently the debugger can only work with one of the other.
But now the browser keeps telling me about the same exceptions even though I've disabled script debugging and have de-selected 'Display a notification about every error'.
So how do I stop Visual Studio from telling me about numerous Javascript exceptions that I can't do anything about? Why can one not just configure it to, 'do not debug javascript from the following domains'?
