I have this working perfectly
[Required(ErrorMessageResourceName = "ValidationError_Required", ErrorMessageResourceType = typeof(Resources.Resources))]
public string Title { get; set; }
public class LRequiredAttribute : System.ComponentModel.DataAnnotations.RequiredAttribute
[code]...
This part of code works fine
[Association(Storage = "profile", ThisKey = "UserId", OtherKey = "UserId")]
public Profile User {
get { return this.profile.Entity; }
set { this.profile.Entity = value; }
}
but if i add in this class System.ComponentModel.DataAnnotations then, Association could not be found.
In mvc1, we can write an attribute as '[NewPath("mainpage", Controller = "BrowsePdts", Action = "Index")]' before Action for 'mappaththen we can do sth. as 'mappath' in webformI just want a navigate in the top of page , as ' book
>> magazine >> fashion 'but what the attribute change to in mvc3?
In my application, I want all dates to display in the MM/DD/YYYY format and I also want the text box to be limited to 10 characters and have a certain class applied to it.
To that end, I made a custom editor template for Date that looks like this:
@ModelType System.Nullable(Of DateTime)
@Html.TextBoxFor(Function(d) d, New With {.class="polkDate", .maxlength="10"})
Then in my view I just can just call @Html.EditorFor(Function(m) m.someDate) and this works pretty well. However, because I'm using TextBoxFor, it doesn't respect the DisplayFormat attribute that's applied to my model class (i.e. it's spitting out the time as well instead of formatting the date).
I would love to use EditorFor so that it would respect the formatting that I want, but you can't add attributes like class and maxlength. I also tried just using the plain old TextBox helper, but I don't know how to make it generate the correct ID so that model binding still works.
I've built a class that derives from System.Web.UI.WebControl. It basically renders pagination links (same as what you see on top of GridView when enabled) for use above a repeater.I'm creating some anchor tags explicitly inside my nav control obviously, but they don't perform ajax postbacks. My understanding is that ajax requires POSTS to work right? Well, these would be GETs
View 2 RepliesI wanted to create a CurrentUser object to be accessible in every Action of Controller, I initialized it in Constructor but User.Identity was not available in Constructor. I followed the following link on stackoverflow:

I am accessing this xml file by using LINQ to XML in asp.net by using C#. I am able to access all the attributes of an XML node by explicitly specifying the name of the attribute. I want to write query on this xml file which reads all the attribute values of the xml node (In our example the node is SERVER) dynamically means I want to write the query which can read the read the value of the attribute Name & ID from first node, only name from second row, Name, ID & Parent from the third row , Name & ID from the fourth row, Name, Parent & Value from the fifth row & only Name from the sixth row without modifying the existing code every time. Once I add one of the attribute ( for example if I add the attribute ID in the sixth row ) in the above xml file then I dont need to modify my LINQ to XML query. My query should dynamically fetch the total number of attributes & display their values. Is their any way to do this ?
I'm building an MVC 2 application with a MySQL database behind it. I've imported the model by adding an ADO.NET Entety Datamodel. Now I want to use DataAnnotations to validate the user input. So I have added the line

However, It just doesn't do anything. The Model.IsValid() returns true no matter how long a string I submit.

I am using business objects that are accessed via webservices. These objects can be loaded via the webservice and serialized to my mvc app. The mvc app can get a web reference to the objects and they can be utilized in the mvc app. However, the business objects are where the classes are defined, and where the annotations are applied.
The mvc validation seems to have no idea that there are System.ComponentModel.DataAnnotations attributes applied to this business object class.
1) Are DataAnnotations lost when objects are serialized / deserialized?
2) If in mvc I use a view model approach, and have nested objects (which themselves have public properties - decorated with DataAnnotations) can/will the mvc validation system traverse the entire object model, the model being used for my view? (so it can see DataAnnotations attributes of the nested object)?
I am using Entity Framework with partial classes added on so I can use DataAnnotation attributes. Does anyone know how to add a data annotatin which will verify that a field is a whole number (or a DataType of int or long)? I'm surprised there is no [DataType(DataType.Integer)] attribute. I tried to create a custom attribute, but it doesn't work because the value it receives is always null:
[code]....
Obviously I'm missing the point, but I don't know enough to know what I'm missing.
I have a DateTime property in my model and I would like to validate it using DataAnnotations.In my view I want to get that DateTime as a number of days (e.g. "3"), instead of a DateTime (e.g. "7/14/2010"). If user enters "3" in the view, then DataAnnotation finds it invalid -and that is the issue.What are my options in this scenario?

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.
View 1 RepliesI have a few field in my entity that i wish to be non-editable. Looking in the docs it seems like "EditableAttribute" would do the trick. However this is only 4.0Just wondering if there are other attributes that would have the desire effect.

View 2 RepliesI have a problem with server-side validation in xVal. I'm using the RequiredAttribute from DataAnnotations.
I would like to change error message from:
The field is required.
to:
Polje je obvezno.
My current solution is this: [Required(ErrorMessage = "Polje je obvezno.")]
But I was wondering if it's possible just to write [Required] and to override error message in one place? (like there is a localization file for client-side validation in xVal)
Is it possible to add a CSS class from DataAnnotations (metadata) when I use Html.EditorForModel() - without a custom template...
Something like this [DataType(CssClass = "DateTime")]
public class TestInput
{
[Required(ErrorMessage = "Name is required.")]
public string Name { get; set; }
[Required, StringLength(500)]
[DataType(DataType.MultilineText)]
public string Description { get; set; }
[Required]
[DataType(CssClass = "DateTime")]
public DateTime Date { get; set; }
[HiddenInput(DisplayValue = false)]
public int Id { get; set; }

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 in my viewmodel class:
[Code]....
In my view I enabled client-side validation.
[Code]....
So, is this the way it's supposed to work? Shouldn't enabling client-side validation highlight non-validating elements by default, without an needing to create an associated Html.ValidationMessageFor(), if it has a DataAnnotation validation attribute?
I'm building an application using MVC 3 and Entity Framework 4. I've created my Entity Data Model and generated a database from it. Now I know the validation attributes such as [Required] or [StringLength(5)] can be used on the model properties to provide validation both clientside and serverside.
I would like to know if these attributes can also be generated dynamically instead of having to add them to the model explicitly? I saw that in EF 4.1 RC you can make use of the Fluent API to further configure your model in the OnModelCreating method by using the DbModelBuilder class. As shown here I'm working with a framework however that still uses ObjectContext instead of DbContext so I would like to know if the above solution can be used in combination with ObjectContext?
As a final note, since I've been trying to figure out how to generate and use data annotations it seems using view models would increase the complexity of validation. From what I read here it seems that just passing the models directly to the view would remove the need to add annotations to the models as well as the view models. However that means that you can no longer use strongly typed views when you do joins on the models and pass those to the view directly?
My case:I am developing an application that will run for multiple clients, each client has the ability to customize field displays and error messages.My issue:I created some custom attributes which inherit from DisplayNameAttribute, RequiredAttribute etc... and in them I am pulling out the resource needed.However it is only executed the once, so if my context changes it will be pulling the incorrectly cached value instead of pulling the new value need.Has anybody attempted to try something like this with the data annotations? Or any advice such as just don't use them for this scenario?

Summary: DataAnnotation's automatic handling of an "int?" is making me rethink using them at all.Maybe I'm missing something and an easy fix but I can't get DataAnnotations to cooperate. I have a public property with my own custom validation attribute:
[MustBeNumeric(ErrorMessage = "Must be a number")]
public int? Weight { get; set; }
The point of the custom validation attribute is do a quick check to see if the input is numeric and display an appropriate error message. The problem is that when DataAnnotations tries to bind a string to the int? is automatically doesn't validate and displays a "The value 'asdf' is not valid for Weight."For the life of me I can't get DataAnnotations to stop handling that so I can take care of it in my custom attribute.This seems like it would be a popular scenario (to validate that the input in numeric) and I'm guessing there's an easy solution but I didn't find it anywhere.
