Description
Indicates the validity of a specified bookmark.
This function returns false in all cases, indicating that any bookmark is invalid because the TDataSet class does not implement support for bookmarks.
Descendant classes that implement bookmark support override BookmarkValid to test bookmarks for validity and indicate when a bookmark is valid by returning true.
