DisplayFormat in TuniDBText not showing?

[erich.wanker]

Hy,

i use following line to set a display format to a field

(unimainmodule.Z_REPORTE.FieldByName('Istkosten') as TNumericField).DisplayFormat := '###0.00 €';

    field 'Istkosten' in unidbgrid shows 10,00 €
    field 'Istkosten' in UniDBText shows 10

why is the same field displayed in two differnt styles?

 

Mysql Database ... field definition  

Istkosten	double(16,2)
