TDBCheckBox.DataChange procedure
Updates the control display value when the linked dataset is changed.
Declaration
procedure DataChange(Sender: TObject)Arguments
Sender | Object for the event notification. |
Description
DataChange is used to perform actions needed when the linked
dataset for the control has been changed. In TDBCheckBox, this requires
setting the
State property for the control. DataChange calls the
GetFieldCheckState method to get the value for the State property.
DataChange is assigned in the constructor as the OnDataChange
event handler in the internal TFieldDataLink instance for the
control. It is temporarily unassigned (when used) prior to calling
GetFieldCheckState, and reassigned prior to exit.
