ADataset |
|
Dataset to check. |
True if the datasource is linked to ADataset.
IsLinkedTo checks if it is somehow linked to ADataset: it checks the Dataset property, and returns True if it is the same. If not, it continues by checking any detail dataset fields that the dataset possesses (recursively). This function can be used to detect circular links in e.g. master-detail relationships.
