TVirtualTable.Assign(ADataset) doesn't retrieve DisplayLabel

TVirtualTable.Assign(ADataset) doesn't retrieve DisplayLabel value.

Exemple :
Code: Select all
ADataset.Fieldbyname('MyField').DisplayValue := 'Hello';

will display
'MyField' instead of 'Hello'

Is it a bug ? If not could you implement this in the next TVirtualTable version ?

This is not a bug. The Assign method of TVirtualTable component creates only FieldDefs based on fields of the source dataset. TFieldDef class does not have DisplayLabel property. When VirtualTable is opened, fields are created from FieldDefs. No properties are copied directly from fields of the source dataset to fields of VirtualTable.

We'll consider possibility of implementing this functionality in a future TVirtualTable version.

Thank you for the answer, I'm really waiting for such improvement (it will be great to add Master / detail feature too ;) )
