Indicates the validity of a specified bookmark.

Pascal
function BookmarkValid(Bookmark: TBookmark): Boolean; virtual;
C++
virtual __fastcall Boolean BookmarkValid(TBookmark Bookmark);
Description

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.
