MVC :: Re Validating Model Data When Using Data Annotations?
Apr 18, 2010
I am using Data Annotations in ASP.NET MVC2 for data validation.There are cases where Model is invalid in Control Action method, by the time I received it. So I add defaults [where data is not present in cetain scenarios, for valid reasons. Other times it is error].All I want to do at this point is, because I updated the model, I want to re-validate model - so that it re-applies all validation again as per data annotations.
If I call Controller.ValidateModel method, I am getting exception saying, it cannot take the model object or type is not correct.If I don't re-validate, my Model.IsValid is false -even though I set up defaults.I am wondering if there a way I can call to re-validate model, from in-side a controller action?

I have various questions about validation using data annotations. I am using the following setup
asp.net mvc 2
entity framework 4
data annotations
Basically, I'm trying to get unique validation working and i'm a little confused. My models are as follows:
public class Buyer
{
public int Id { get; set; }
[Required(ErrorMessage = "The email is required")]
public string Email { get; set; }
[Required(ErrorMessage= "The name is required")]
public string Name { get; set; }
}
public class Seller
{
public int Id { get; set; }
[Required(ErrorMessage = "The email is required")]
public string Email { get; set; }
[Required(ErrorMessage= "The name is required")]
public string Name { get; set; }
}...............................................

I've been used to decorating data model classes with data annotation attributes, but the purist in me baulks slightly at including purely presentational attributes such as display format here. I am, however, quite happy to keep validation centric attributes here. One good reason I have to continue keeping all annotations etc. in the data model is that my view model aggregates data model classes, e.g.
my ViewModelBase.DetailItem<TEntity> property in the view model is just a reference to an entity class in my data model. If I wanted to move presentational annotations to the view model, I would have to quite radically revise my design to one where I duplicate data model properties in my view model and use an object mapping tool to populate view model objects based on data model objects.

I make use of validation with data annotations in my model classes. How do I make sure this annotations are not violated when I validate data in my business layer, before sending it to the DAL? I guess I don't want to define the validation rules in two places (model classes and in my BLL-classes)?

My team is building ViewModels with model validation inside the MetadataType. My question is that I'm using a non-MVC project, can I use it to validate the model?
[MetadataType(typeof(PersonMetadata))]
public class Person
{
public int ID { get; set; }
public string Name { get; set; }

I would like to know if it's possible to bypass the validation of one property which is using Data Annotations. Since I use the model across multiple pages, there's a check I need in some, but not in others, so I would like it to be ignored.

Defined RegisterModel class - with some validation rules for creating new users, and this works fine.
Then I get this class, strip few properties and wanted to reuse it as UserInfo_Form_Model, for editing user properites.
No changes, just deleted few items, renamed and reused in strongly typed View for editing.
And result of validation is: -
[DisplayName("Name")] works fine, showing correct
[StringLength(20, ErrorMessage = "xxxx...")] - not working, no message showed when suppose to be one
[Required(ErrorMessage = "xxxx.")] - not working, not showing messages when delete required values?
but (ModelState.IsValid) is false when I checked it in controller (it had to be because required value is missing)?
Is it this only partially correct and how this can be?
Well this is a bit frustrating because it cant be simpler than this and I cant make this simple code reuse.

If I have a search object with a list of fields, can I, using the System.ComponentModel.DataAnnotations namespace, set it up to validate that at least one of the fields in the search is not null or empty? i.e All the fields are optional but at least one should always be entered.

I have this attribute in my view model:
[DataType(DataType.DateTime)]
public DateTime? StartDate { get; set; }
If I want to display the date, or populate a textbox with the date, I have these:
<%: Model.StartDate %>
<%: Html.TextBoxFor(m => m.StartDate) %>
Whenever the date is displayed, it's displayed like: 01/01/2011 12:00:00 AM
But I'd like to only display 01/01/2011
Is there a way to apply a display format with data annotations? I don't want to have to go to every instance where I display a date, and add some code to format it.

I am trying to make some sense of this validation stuff in MVC2. I followed various walkthroughs, all them for betas/rcs... and I cant' get anythign to happen. Note: THIS JQUERY - NOT THE MS AJAX STUFF!I have referenced MicrosoftMvcJQueryValidation.js which i got got the mvc2 futures lib.
My model is:
[Code]....
The form bit of my ViewPage<User>:
[Code]....
As far as I can see the only additional thing that is being rendered is this:
[Code]....
Which is interesting/annoying for a few reasons. Firstly all of my annotations appear to have been ignored.Secondly FormId isn't even marked as required, and as this rendered text was taken from a page loaded with a null Model (add mode) the FormId field isn't in the form. Finally, this doesn't even result in any actual validation occuring (on the client side). All the server side validation is working fine.See I am using PasswordFor instead of EditorFor. Because someone at MS testing dropped the ball there. Yes EditorFor renders a password field, but it behaves differently to PasswordFor.. the value of the Password field is sent to the client (set in the value
attribute of the field). Fail.

Basically I have RegisterModel2 that has a Person class. My requirement is that Phone Number and Address are not required for registration. But if they try to enter a Phone number of Address then it should validate it. Problem is that it is always stating that the child fields of Phone (area code, number) and child fields of Address (street1,city,etc) are required. Is there a way to annotate in the RegisterModel that a parent class is not Required but if any data in a child element is given then and only
then should the child elements be validated?
My Person EDM class has a nullable 0.1 -> 0.1 navigation property to Phone and Address.Here is the person class
[MetadataType(typeof(Person_Validation))]
public partial class Person
{
}
public class Person_Validation [code]....
The Person EntityObject has an optional/nullable Navigation Property to the Phone Object.
The Phone object has these annotations,[Code]....
I have RegisterModel defined as follows:

My View looks like this:

And here is my Controller Action it is posting to:

I have a Car class that I'm trying to display in an MVC 3 view using the WebGrid helper. Below are the Car and it's metadata class.
Car class:
[MetadataType(typeof(CarMetadata))]
public partial class Car
{
// car implementation
}
Car metadata class:
public class CarMetadata
{
[DisplayName("Car Name")]
[StringLength(100, ErrorMessageResourceType = typeof(ValidationText), ErrorMessageResourceName="CarNameDescriptionLength")]
[Required]
public string CarName { get; set; }
}
View contents:
@model List<Car>
...
var grid = new WebGrid(Model, canPage: true, rowsPerPage: 10);
grid.Pager(WebGridPagerModes.NextPrevious);
@grid.GetHtml(
htmlAttributes: new { id = "grid" },
columns: grid.Columns(
grid.Column("CarName", ?????)
));
GOAL: I'd like to figure out how to use the DisplayName data annotation as the column header text in the WebGrid (?????). Does anyone know how this is accomplished?

I m Using a GridView: Columns: "Ser_type" tells what type of data is it i.e. VC for Varchar, NU for Numeric, DT for DateTime etc, for the time being i m using datavalidation controlls at design time. this is not a good approach. I just wan to do is that, DataValidationControlls should be created at RunTime and TextBox should validate data at runtime only. i.e. if Data required in the TextBox is of Type VC then it should validate only at runtime, if DT then validate DateTime only at Runtime similarly for all dataType:

quick question: I have a view on my HomeController which is used to create a new 'model'. This view posts to a different controller to keep things tidy. The problem I am having is when I enter invalid details into the form, the rules I specified never seem to make it back to the original view and thus my validation messages or summary never get populated. Is there a way around this because I am using a view model with two IEnumerable lists in it.

In my view data class I have a List.
[Code]....
I have all the properties of the class Person as required using Data Annotations.
[Code]....
In the View I loop the List like this:
[Code]....
Generated HTML:
[Code]....
Result:
Does not work at all.
Other things I've tried:
Tried using these HTML Helper methods instead:
[Code]....
Generated output:
[Code]....
Result:
Interestingly, when I trigger a validation on the first textbox, it fires simultaneously for all of the textboxes. The rest of the textboxes do not trigger validation at all.
Looking at the generated id and names for the textboxes and their corresponding error text span element, they areall identical.
Anyone figure out how to use Client Validation with Data Annotations with a List in the view data,
supporting Model Binding?

I am using a bound gridview in ASP.NET 2.0. The gridview has the ability to edit/update and insert rows. One of the columns holds a number which represents a percentage. What I cannot figure out is how to ensure that all the rows in the gridview total 100% before being able to send the updates or newly inserted data to the database.
For example say there are 5 rows in the gridview, each row has 20% stored in the column so it adds up to 100% which is fine, the data is updated/inserted in the database. But say each row only had 15% totalling 75%, the user should not be able to send the updated/inserted data to the database until either they add a new row with a percentage of 25 or they edit the other rows for a cumulative total of 100%

I'm using an entity model with metadata annotations. My controller method looks like this...
if (!ModelState.IsValid)
{
return View(model);
}
else
{
UpdateModel(model);
repo.Save();
return RedirectToAction("Index");
}
If I enable client side validation in the view I'll get the error per the Attributes from the metadata class. If I take clientside validation out, error gets thrown from saving to the DB rather than return the view with an Error Summary.
This is the top portion of my view....
<% using (Html.BeginForm())
{%>
<%: Html.ValidationSummary(true) %>
I've tried running without debugging (ctrl + f5) in debug and release mode as well as setting breakpoints and Debugging (f5) but it just seems weird to get Client side validation without server side validation. What am I missing here?
