RAD Studio VCL Reference
TDataSet.Designer Property

Returns a pointer to the DataSet designer for the dataset.

property Designer: TDataSetDesigner;
__property TDataSetDesigner Designer;

Use Designer to determine whether the dataset is currently being designed and, if so, to access the dataset designer. When a dataset designer, such as the Fields editor, is created for a dataset at design time, it sets the Designer property to itself. When the dataset designer is destroyed, the Designer property is set back to nil (Delphi) or NULL (C++). A DataSet designer enables a developer to specify the fields that belong to a dataset at design time.
