Good afternoon,
I was trying to create a sample project with a Master / Details and POCO's and am having a problem.
The property (EntityAspect) of my Detail is always with the null value. What am I doing wrong?
Could you send me an example to work or see
what's going on with my example?? SalesOrderHeader: using System.Collections.Generic;
using System.ComponentModel;
using System.ComponentModel.DataAnnotations;
using System.Runtime.Serialization;
using IdeaBlade.EntityModel;
namespace SalesPoco
{
[DataContract]
public class SalesOrderHeader : IHasEntityAspect, INotifyPropertyChanged
{
[Key]
[DataMember]
public int SalesOrderID
{
get { return _SalesOrderID; }
set
{
_SalesOrderID = value;
OnPropertyChanged("SalesOrderID");
}
}
private int _SalesOrderID;
[DataMember]
public int CustomerID
{
get { return _CustomerID; }
set
{
_CustomerID = value;
OnPropertyChanged("CustomerID");
}
}
private int _CustomerID;
[DataMember]
public decimal TotalDue
{
get { return _TotalDue; }
set
{
_TotalDue = value;
OnPropertyChanged("TotalDue");
}
}
private decimal _TotalDue;
[DataMember]
public string Comment
{
get { return _Comment; }
set
{
_Comment = value;
OnPropertyChanged("Comment");
}
}
private string _Comment;
[DataMember]
[Association("SalesOrderHeader_SalesOrderDetail", "SalesOrderID", "SalesOrderID")]
public List<SalesOrderDetail> SalesOrderDetails
{
get { return _SalesOrderDetails; }
set
{
_SalesOrderDetails = value;
OnPropertyChanged("SalesOrderDetails");
}
}
private List<SalesOrderDetail> _SalesOrderDetails;
