RAD Studio VCL Reference
TDataSet.Modified Property

Indicates whether the active record is modified.

property Modified: Boolean;
__property Boolean Modified;

Check Modified to determine if the active record is modified. If Modified is true, the active record is modified. If false, the active record is not modified.

Note: In general, an application need not check the status of Modified. Properties, events, and methods of TDataSet and its descendants that modify records generally check this status automatically and take appropriate actions based on its value.
