Hi, I have an entity called person. In the entity class I have made a property that is called FullName get{this.Lastname + ", " + this.FirstName}

and I was wondering how I could make this available in the fields collection

meaning: I can access things like this

IEntityCollection2 inCollection; inCollection[0].Fields["FirstName"]

but I would like to be able to access the FullName in this manner so inCollection[0].Fields["FullName"]

Is there a way to accomplish this?

Thanks in advanced

Take a look at the step 6 of this Frans Bouma's article.

Thanks, that works perfectly but I need advice on a small issue

my expression for the field looks like this:

IEntityField2 fullNameField = new EntityField2("FullName", new Expression(Person.LastName,ExOp.Add,Person.FirstName));

that works but it returns SchmoeJoe I need the expression to return Schmoe, Joe. How do I achieve this.

sorry, I am new to the expressions code

also, we are regenerating code a lot. how do I stop the new code from being deleted on a regen

public virtual IEntityFields2 CreateFields()
        {
            //__LLBLGENPRO_USER_CODE_REGION_START
            IEntityFields2 fieldsToReturn = EntityFieldsFactory.CreateEntityFieldsObject(HOO.LARS.BLL.EntityType.person);
            fieldsToReturn.Expand(1);
            IEntityField2 fullNameField = new EntityField2("FullName",
                    new Expression(personfields.LastName,ExOp.Add,personFields.FirstName));
            fieldsToReturn.DefineField(fullNameField, fieldsToReturn.Count - 1);
            return fieldsToReturn;
            // __LLBLGENPRO_USER_CODE_REGION_END
        }

normally it looks like:

return EntityFieldsFactory.CreateEntityFieldsObject(HOO.LARS.BLL.EntityType.VO_CrewMemberEntity);

I now my code shouldn't disappear but I dont want the code above to be placed in front of mine again

Everything in CODE_REGIONS is kept between generations. No worries You also could (and should if possible) use partial classes.

duh, that code makes complete sense

thanks alot man.

thanks, got it.
