public procedure TFieldDataLink.Modified; |
Modified is a procedure which updates the class when the linked dataset is placed in an edit state. Modified sets the value in the internal IsModified member to True to track the state change independent of the real state for the linked dataset.
The EditingChanged, UpdateData, and Reset methods reverse the action performed in Modified.
Modified is used in the implementation of methods in data-aware controls, and generally occurs just prior to calling the Change method to signal an update to the value for the control.
