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.
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]...
When should we add this attribute to an asp.net webservice ?
[System.ComponentModel.ToolboxItem(false)]

I have a 1:M relationship between Contact and EmploymentHistory.I want to create a new association that is the current employment, which would be 1:1 so I can do Contact.CurrentEmployment.The EmploymentHistory table has a CurrentEmployment flag.Is there a way to do this in Entity Framework?
View 1 RepliesI have 3 tables 1-Category, 2-AssignToCategory, 3-User
Fields in Category (Id, CategoryName)
Fields in AssignToCategory (Id, CategoryId, UserId) -->CategoryName,UserId as forigen key
Fields in User (Id, Fullname)
There is no association defined just used forigen keys.Impoted in EF. Now I want to create association.
1 - Right Click on User and Category for association and 1 to many created UNCHECKING FK checkbox as foriden keys already defined. Relation created than double clicked on relation to assign Principal and Dependent key (Principal (User,Category) and Dependent is AssignToCategory). All done.
Error
Error 1 Error 113: Multiplicity is not valid in Role 'User' in relationship 'UserAssignedToCategory'. Because all the properties in the Dependent Role are nullable, multiplicity of the Principal Role must be '0..1'. c:userslordalidocumentsvisual studio 2010ProjectsCodingCodingModelsCoding.edmx 93 11 Coding
Same error for Category.How do i create association if its not defined on imported tables.
SIDE NOTE: If I removed forigen keys from AssignToCategory and created an association with FK check box clicked so EF put the forigen keys than everything is fine.
I have implemented the File Upload (upon reading Scott Hanselman's excellent post)I have multiple files associated with various questions on the form though, and would like to associate each saved file with an internal ID.
How can I do this? For example, if question # 3 has a file uploaded abc.pdf, how can I associated that file with ID #3?
I have two tables I am using to fill a gridview. The tables have a common field named RangeActivityID. My problem is that the database is very old and some of the older entries do not match up IDs between tables, so I am unable to add an association between them in the database.
I do not care about the old data which doesn't match up, so in my .dbml file, I manually created an association in order to select good data from both tables. This is the LINQ query I have:
var collective = from p in rangeConnection.RangeActivities
orderby p.RangeActivityID
select new
{
TestName = p.TestName,
DateTime = p.ActivityDateTime,.......
I can set my grid datasource to 'collective' and everything works, but if I uncomment the three commented lines, the query returns no results because the tables have data that doesn't meet the association criteria. Is there a way to have the LINQ query ignore results that do not match up?
is it possible to have a button defined outside a grid view and give it a command name of "select" and somehow attach it to the gridview, so the grid recieves a select command when clicked without writing code?
View 5 RepliesI have a Listview that is connected to an EntityDataSource. What I'm having trouble doing is showing fields of an association in the Item Template rather than just the id.
For example, what it currently shows:
Name: John Doe
Race: 3
What I wish it would show
Name: John Doe
Race: Caucasian
Some example code:
[Code]....
Obviously, I'm getting the number because Race_ID is an integer. What I'm less sure about is how to bind it or Eval it in some manner that will let me match that id to a name in the other table (which is associated). I've tried <%# Eval("Race.Name") %>' and a few other things to try to get a name rather than an ID but I always get either the id or nothing at all.
I,am trying to create a self association relation for an organization chart data tree in Entity Framework,after trying different ways for prevention of exceptions like 3007 and etc. I found that when I put my foreign key in my POCO near Parent and Items navigation properties its work.but I think this is not correct that we have both ParentID scalar property and Parent navigation property. review this and tell me is it correct or not.I'm using VS 2010 RC and ofcource .net framework 4.0 RC

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?
View 2 RepliesUsing data annotations for asp.net MVC, I can enforce range, regular expressions, required, stringlength, etc.. However, I have boolean property "SignedDocument" that I want to enforce its set to true? Is this possible in data annotation?Example:

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. So be clear, i have a field called "DateRegistered" i wish to display this as string not text field using "Html.EditorFor"
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 got a Category model and it looks like this
[Code]....
My problem is that when i do a tryupdatemodel it validate the ParentCategory aswell, is it really suppose to do that? How could i avoid this, I tried [Bind(Excluede = "ParentCategory)] in the ActionResult but with no luck. I have looked all over the place with no luck everybody just got the Id problem.
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.

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 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?
