Registering a backing DataEntityProperty for a custom property looks something like this:

 

public partial class Customer {

  public string FullName {
    get { return PropertyMetadata.FullName.GetValue(this); }
  }

 

  public new partial class EntityPropertyNames  {
    public const string FullName = "FullName";
  }

 

  public partial class PropertyMetadata {
    public static readonly DataEntityProperty<Customer, string> FullName =
    new DataEntityProperty<Customer, string>(
      propertyName: EntityPropertyNames.FullName,
      isNullable: false,
      isPartOfKey: false,
      concurrencyStrategy: ConcurrencyStrategy.None,
      isAutoIncrementing: false,
      relatedNavigationPropertyName: null,
      isNativeProperty: false);
  }
}

 

The problem is that once you've tied into the PropertyMetadata you won't be able to use a simple property getter like you're probably now using, but will need to do some sort of property interception.  Something like this:

 

[AfterGet(EntityPropertyNames.FullName)]
public void FullNameGetInterceptor(PropertyInterceptorArgs<Customer, String> args) {
  args.Value = FirstName + LastName;
}

 

If this all looks like more than you need, then simple reflection will also allow you to get and set your custom property from your entity base class.

 

I've created a custom string property "strFullName" on my entity which basically just returns a concatenated string of several properties such as "strLastName", "strFirstName", and "strMiddleName". I created a generic method that access my entity base, and from here I can only access the EntityAspect property of my entity (not actual field names..). So when I try to access the fields strLastName", "strFirstName", and "strMiddleName", I am able to, but not "strFullName". It throws me an error "DataProperty: 'strFullName' does not exist on type 'EntityAspect'". How can I make it so that I can be able to check the value by using this code?
