Table (or CDS) Field DisplayFormat

2.3k views Asked by At

When adding persistent fields of a dataset using the Fields Editor, the field names are concatenated to the dataset as TableMyField, I can then access the persistent field's DisplayFormat property in my code as:

TableMyField.DisplayFormat

However, if I don't use the Fields Editor and don't use persistent fields, how can I access the DisplayFormat property at run time?

Since the DisplayFormat property is contained in descending classes of TField, you'd need to cast at runtime. You can do this a couple of different ways.

TNumericField(Dataset.Fieldbyname('CostPrice')).DisplayFormat := '#,###.00';

(Dataset.fieldbyname('CostPrice') as TNumericField).DisplayFormat := '#,###.00';

TNumericField(Dataset.fields[0]).DisplayFormat := '#,###.00';
