There's a way to set the default resource to the data annotations validations?I don't wanna make something like this:
[Code]....
I would like something like this:Global.asax

In our web application we need to keep various company's settings. For eg "DiamondProdRefIDCaption","Shippingpickup","ZipCodeCaption","DefaultCountry","AllowToEditInvoice", etcThese settings are different for various companies and are placed in web.config as key-value pair.Initially, we have tried do simplify this process by adding a company_settings table in the DB so as to allow us to add companies on the fly. However, this method makes it very difficult to add a new setting
<%$Resources:DiamondProdRefIDCaption%>
What I want to do is to use the default web resource inside asp.net. For example, If I create a web page with a simple Wizard control and 4 WizardStep ( Start,Step,Finish and Complete) it create a translation of navigation button with the culture of application.
But, for example if i want to create a custom FinishNavigationTemplate I can't (or I don't know how) use the default asp.net transaltion.
How can I use the default asp.net translation (or web resource) for my custom template?
I am using VS2010 RC and i created a buddy class. My problem is that i cant seem to see the option to change the Display name of a column.i only see "displaycolumn" and "displayformat".
View 7 RepliesI 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.
View 2 RepliesI 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 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)?
View 6 RepliesDefined 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.
View 2 RepliesI 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.
I'm creating a Asp.Net MVC application and I need help on whether I should chose Data Annotations or Service Layer Validation (e.g. if(Model.Name.Trim().Length == 0)?
View 5 RepliesI 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?
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.
View 5 RepliesIn my view data class I have a List.

I have all the properties of the class Person as required using Data Annotations.

In the View I loop the List like this:

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 would like to use DataAnnotations in my ASP.NET MVC application. I have strongly typed resources class and would like to define in my view models:
[DisplayName(CTRes.UserName)]
string Username;
CTRes is my resource, automatically generated class. Above definition is not allowed. Are there any other solutions?
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?
How can I use an image or icon resource from global resource file in an asp:Image control to set the ImageUrl attribute?
View 1 RepliesI will be setting the current thread's culture at the beginning of the request lifecycle.
Does it make sense if I create my own resource.xml to store things like strings/labels/messages that will be used in the web application?

I have a webservice that supplies data (Publisher Object) to a silverlight project.
I want to bind the Publisher to a dataform and have the dataform handle to validation.
I would like to achive this by using DataAnnotations.
My question is..
Can I or how do you amend the Publisher object (Generated by the webservice) to add the DataAnnotations
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?
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 been working in a web applciation and want to annotate the image downloaded from the server at client side and once the user have added some text into the image that specified images must be saved on the server so that while rereving those images user should be able to view the annotated imags.How to achieve the above target.?I have tried following link which is in Jquery and add the annotations in the images...but it last until user close the browser.
http://code.google.com/p/jquery-image-annotate/
Besides this,they also given a solution to implement it the server side in the below link;
http://blog.flipbit.co.uk/2009/04/server-side-ajax-handler-for-image.html
But, the code written is using c# in MONORAIL..infact i could not understand the save,delete operations of the annotations. i been searching for the solution for more than a weak but could nt get it yet.. it using silverlight but as I am quite new to silverlight so send me some useful links for the same.
Get function as on call of save function and delete function the annotation's entry would be updated in the database.But, The Get function is not drawing the marked annotations on the image.How it would work.?
View 6 RepliesI can currently populate and display a Drop Down using the following model annotations, viewmodel, and custom Editor template - but am having problems persisting the submission (more on that below):
//Domain
Public class Person
{
public string FirstName {get;set;}
public string LastName {get;set;}
public string ClassName {get;set;}
public int ClassId {get;set;}
...
}
//ViewModel
Public class PersonViewModel
{
public Person Person {get;set;}
Like I mentioned, the above works fine - as in the drop down is displayed properly, but obviously in its current state it's not saving the classID (or name) to the Person entity, I understand the problem but not sure how to fix it.
My questions:
How can I save the selected value from the drop down to the Person entity
How can I save both the ID and the Name into the Person entity - I'm guessing only way is a hidden field that gets populated with an onchange event (this sounds weird, I'm sure, but it's being stored in a document DB, so it's not normalized - I may just store Name in the end)
