Disable DataAnnotations Validation On DefaultModelBinder?
Mar 16, 2010
I want DefaultModelBinder not to perform any validation based on DataAnnotations metadata. I'm already using DataAnnotations with DynamicData for the admin area of my site, and I need a different set of validation rules for the MVC based front-end. I'm decorating my classes with the MetadataType attribute. If I could have different MetadataType classes for the same model but used on different scenarios that would be great.If not I'm fine with just disabling the validation on the DefaultModelBinder, either by setting some property or by creating a specialized version of it.

I'm having problems with getting my custom dataannotations to work, I'm trying to add a validation-attribute that validates that the UsergroupName for a Customer (CustomerID) is unique.
[Code]....
the IsValid should return false if the "count >0". How do I fix this one so it works. GetUsergroups() returns IQueryable<Usergroup>.

I have tried everything to get client-side validation to work in MVC2 RC, but have been completely unsuccessful. Server-side validation works just fine, but client-side never fires. I have grabbed
[Code]....
from the futures source, since it wasn't included in RC. Unfortunately, that's the only script that people agree is necessary for everything to work. Besides that, nobody seems to know which other specific js scripts are needed. The candidates are (jquery-1.3.2.js, jquery.validate.js, MicrosoftMvcAjax.js, MicrosoftMvcJQueryValidation.js). I've tried every permutation of these and other scripts to no avail.
Html.EnableClientValidation() has been included before BeginForm, and the JSON validation data appears to be correctly written into the source of the page. But, again, client-side validation never fires.

I'm using DataAnnotations as well as server-side validation logic.
Is there a way to show DataAnnotation's client-side validation errors in the ValidationSummary, as it shows when returning from server validation?
I know I can use ValidateMessage and ValidateMessageFor next to elements, but the spacial design of the form I'm working with doesn't allow for anything other than highlighting the HTML element, however, I would still like to have a message saying what's wrong.
If I place ValidateFor's alongside ValidationSummary in order to mimic a ValidationSummary during client-side validation, they both appear when returning from a failed server side validation.

I am having a problem with the Client Validation not firing when I have marked a nullable DateTime field as [Required] and the value of the field is null. (It is actually stopping ALL client validation on the page working - not just the DateTime field).
Interestingly enough, once a post back has been done and the error picked up on the server, the client validation starts working.
Also if you set the date to a none null value (see commented out line in the controller) it will also work
I have replicated this behaviour in a small test project (this is deliberately very Noddy - just enough to replicate the problem)
Am I doing something fundamentally wrong or am I looking at coding some sort of work around here? (I realise that a Required nullable field sounds like a bit of a oxymoron, but I wanted to present the user with a blank field which they must then fill, not one pre-populated with an arbitrary date value)

How can I disable the code behind validation when javascript validation is present? Then if there is no javascript enabled then the code behind validation will do its thing. What I notice is that it's reading the code behind valdiation not the javascript.

What method to override in order to be able to capture the data via a custom modelbinder. I noticed this article:http://www.singingeels.com/Articles/Model_Binders_in_ASPNET_MVC__Part_2.aspx and there GetValue is overridden but I don't see that in MVC 2. What must I do to be able to make this work?

I have a page that has a submit button which causes validation and a cancel button which does not cause validation.
When the cancel button is clicked, the button's click event handler is executed with no problem.
I would like the ESC key to do exactly what the cancel button does.
What we do is to trap the ESC key and then raise the click event for the cancel button.
Our code to handle the ESC key works fine except when the page has a validator.
When the page has a validator, the cancel button click event handler never gets called after the ESC key is pressed.
It works fine when the cancel button is clicked.
It also works fine if we do the same thing and trap any other key.
So it has something to do the ESC key and validation.

I'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.

I have a form where one of the fields would allow entry of HTML tags.
<asp:TextBox ID="someID" runat="server" TextMode="MultiLine" />
In this field I have a RequiredFieldValidator validation only. Unfortunately, after any PostBack if the content of any of the fields includes HTML tags or any other potentially dangerous code - the entire ViewState is cleaned.Setting ValidateRequest to false does not help. I'm using IIS 7.5 and .NET 4.0.

I have a div where I put a lot of stuff on runtime to construct a chart. The user should be able to copy the chart to another div (innerHTML) and then make som adjustments to the original div, which causes a postback. Of cours the cloned div comes back empty.
So I'm thinking of putting the entire innerHTML in a session variable at page_unload, but then I run into the validation problem. I've tried using a hiddenfield as an in-between control, but it's the same, and it seems you can't use the CausesValidation on that control. I've also tried a regular asp:textbox, but the CausesValidation doesn't have any effect.
How to do this? Or any better way all together on the copy-chart issue?

I have orders page. When user submit Order, I need to disable the button to avoid multiple transactions. I also have few validation controls on the page, so button should not be disabled untill page is about to be posted. I dont have any custom javascript for validation. It is just these asp.net validation controls. What is the best way to achieve that? I have spend about 2 hours on google and found various solutions, but nothing seems to work. Each has some issue. On button I add OnClientClick="return btnOnClick this, 'Payment');" Below is what gets called. Unfortunately if I disable button, it cancels post back. So I am calling dopostback and also adding few lines on server side to see which button caused postback. It works fine in IE8 and Chrome. But for Firefox on server side arg comes null. Any ideas what is wrong with my code? Or any other suggestions to do it in a better way?
C# Server side
string arg = this.Request.Params.Get("__EVENTTARGET");
if (arg == "Payment") { this.ProcessPayment(); }
Button
<asp:Button ID="btnSubmitPO" OnClientClick="return btnOnClick(this, 'Payment');" runat="server" Text="Submit Order" ValidationGroup="G" />
alert(group);

I have a form that occassionally submits more than once per user. I am assuming the problem is that the user gets impatient and clicks submit multiple times. I have a bunch of asp validation controls on the page. There is multiple validation groups, the submit button belongs to the "main" group. How do I validate the "main" group, then if the page is valid, disable the button and submit it? I tried adding this.disabled=true; but that just disables it and doesnt submit or anything.

How can I conditionally disable client-side validation of some fields ?
Here is the example of what I need to do:
user writes name and address and submits. Both are validated both server and client side. If validation passes e-mail is send to given address and (name, address) pair is stored.as a response same page is displayed (I don't want redirect!) this time with confirmation. User can retype their name and submit. In such case e-mail will be resend to the address that corresponds to given name.
It does not work because: client side validation will not pass when user clicks resent button on the second (confirmation screen). It would say that e-mail is required even if there is no field for it. How can I disable javascript validating email before the confirm page gets send to user ?
Example ASP.NET MVC page
<%if (Model.Confirm == false){ %>
<% using (Html.BeginForm()) { %>
Your email: <%: Html.EditorFor(m => m.Email) %>
Your name: <%: Html.EditorFor(m => m.Name) %>
<input type="submit" value="Send Email" />
