RAD Studio VCL Reference
TDataSet.NestedDataSetClass Property

Indicates the class type to use when creating nested datasets.

property NestedDataSetClass: TDataSetClass;
__property TDataSetClass NestedDataSetClass;

TDataSet descendants use NestedDataSetClass to specify the class that can be used for nested datasets. By default, this value is the same as the class of the dataset instance. 

NestedDataSetClass is used to check that nested detail sets are the appropriate type when they are assigned to a data set field (by assigning a value to their DataSetField property).
