validateBinding method

  1. @override
void validateBinding(
  1. FdcDataSet dataSet
)

Validates this column's dataset field binding for the grid runtime.

Standard typed columns require one expected FdcFieldDef subtype. UI-specialized columns can accept an explicitly supported set of field subtypes. This hook intentionally returns no package-internal binding object.

Implementation

@override
void validateBinding(FdcDataSet dataSet) {
  throw StateError('FdcActionColumn is not bound to a dataset field.');
}
