Sort DatasetField

HI all,

I would like to be able to order the result of Dataset Fields (Many-Valued Associations).

In the example:

InvoiceDataset.SetSourceList (List);

InvoiceDataset.Manager: = Manager1;

InvoiceDataset.Open;

ItemsDataset.DatasetField: = InvoiceDataset.FieldByName ('Items') as TDatasetField;

ItemsDataset.Open;

I would like to be able to order ItemsDataset for a content field in the dataset, for example the items field itself.

It's possible?
