Hi,

I would like to update a lot of records via a uow.AddUpdateMultiCall(). In this situation i need to add an entity with the values to be updated. So i write:

ActieEntity newValuesVervolg = new ActieEntity();
newValuesVervolg.VervolgActieID = null;

ActieCollection acties = new ActieCollection();
uow.AddUpdateMultiCall(acties, newValuesVorige, ActieFields.VorigeActieID == ID);

The problem is that the InitClassEmpty() of the ActieEntitiy is filled with:

protected override void InitClassEmpty(IValidator validatorToUse)
{
    base.InitClassEmpty(validatorToUse);
    if (Fields.State == EntityState.New)
    {
        Datum = DateTime.Today;
        Gereed = false;
    }
}

We need to add this code in the InitClassEmpty() because the initial values must be refelected in the webpage directly when we create a new record (when we put this in the OnSave() we can't see the initial values).

When i commit the UnitOfWork i see that the following values will be set: - Datum (because of InitClassEmpty()) - Gereed (because of InitClassEmpty()) - and the field VervolgActieID.

The problem is that the values of "Datum" and "Gereed" may not be updated in the UnitOfWork.

Can you tell me what i'm doing wrong?

Regards, Sander

Would you please check the IsChanged property value of each of these entityField?

When i query during runtime:

newValuesVorige.Fields["Gereed"].IsChanged

than "True" is returned...

Please try forcing this fieldsd to IsChanged false.

ActieEntity newValuesVervolg = new ActieEntity();
newValuesVervolg.VervolgActieID = null;
newValuesVervolg.Fields["Datum"].IsChanged = false;
newValuesVervolg.Fields["Gareed"].IsChanged = false;

ActieCollection acties = new ActieCollection();
uow.AddUpdateMultiCall(acties, newValuesVorige, ActieFields.VorigeActieID == ID);

When i set the IsChanged property to false in the OnDelete()-methode and we add a new field to the InitClassEmpty() method in that entity, we can't see we need to add the

Fields["NewField"].IsChanged = false;

statement into the OnDelete()-methode to get the same result. When we add the IsChanged-statement directly into the InitClassEmpty() the fields will not be saved in the database.

Is there another work-around / solution for this problem?

Thanks, Sander

What I tried to say is that you should force the IsChanged property of the problematic fields right before you call AddUpdateMultiCall, not at the InitClassEmpty().

Forcing this will avoid the Datum and Gareed fields being updated, as the problem is, as far as I understood from your first post. Or did I misunderstood that?

BTW, I never mentioned OnDelete()

You're right, you've never mentioned OnDelete(), but that is the place where i need the UnitOfWork

I've made a helperclass with a method SetAllFields2NotChanged() which sets all the IsChanged-properties of the fields to false.

public static void SetAllFields2NotChanged (CommonEntityBase entity)
{
    foreach (EntityField field in entity.Fields)
        field.IsChanged = false;
}

I call this method directly after i create a new entity.

ActieEntity newValuesVervolg = new ActieEntity();
SetAllFields2NotChanged(newValuesVorige);
newValuesVervolg.VervolgActieID = null;

ActieCollection acties = new ActieCollection();
uow.AddUpdateMultiCall(acties, newValuesVorige, ActieFields.VorigeActieID == ID);

This works fine for me, thanks for the advice!
