Question

suppose my edmx file is named School.edmx and it has school.Designer.cs class.
In the designer class i have the folowing entity object

[EdmEntityTypeAttribute(NamespaceName="teamworkModel", Name="User")]
[Serializable()]
[DataContractAttribute(IsReference=true)]
public partial class User : EntityObject
{

    #region Primitive Properties

    [EdmScalarPropertyAttribute(EntityKeyProperty=true, IsNullable=false)]
    [DataMemberAttribute()]
    public global::System.Int32 User_Pk
    {

                OnUser_PkChanged();
            }

I have the following columns in the above entity object (User table)User_PK,User_Name,User_Password,User_Email_ID…..

Please can anyone suggest how to create a viewmodel for the above entity object that contains all the above columns except User_Password and User_Email_ID because i need to use it as strongly typed viewmodel for my view.I also need to use another table in the same viewmodel with selected columns….

i had gone through a lot of documents..i already spent 1 and half day for this
can anybody help..
i know this question is asked repeatedly but i cannt find the right way in doing it…
Thanks

Answer 1

Edit: Modified to answer comment about extra properties from other Entities

This may help

public class UserViewModel
{
public int Pk{get;private set;}
public string Name{get;set;}
public DateTime CreationDate{get;set;}
public string ProjectName{get;set;}
public DateTime ProjectCreated{get;set;}
}

The ViewModel is a flattened version of you entities.
