 Using Multiselect Database Grids - 2.0
When you add [dgMultiSelect] to the Options property of a DBGrid, you give yourself the ability to select multiple records within the grid. The records you select are represented as bookmarks and are stored in the SelectedRows property. The SelectedRows property is an object of type TBookmarkList. The properties and methods are described below. Click here to download an example.
property SelectedRows: TBookmarkList read FBookmarks;
TBookmarkList = class
public
{* The Clear method will free all the selected records
within the DBGrid *}
procedure Clear;
{* The Delete method will delete all the selected rows
from the dataset *}
procedure Delete;
{* The Find method determines whether a bookmark is
in the selected list. *}
function Find(const Item: TBookmarkStr;
var Index: Integer): Boolean;
{* The IndexOf method returns the index of the
bookmark within the Items property. *}
function IndexOf(const Item: TBookmarkStr): Integer;
{* The Refresh method returns a boolean value to notify
whether any orphans were dropped (deleted) during the
time the record has been selected in the grid. The
refresh method can be used to update the selected list
to minimize the possibility of accessing a deleted
record. *}
function Refresh: Boolean; True = orphans found
{* The Count property returns the number of currently
selected items in the DBGrid *}
property Count: Integer read GetCount;
{* The CurrentRowSelected property returns a boolean
value and determines whether the current row is
selected or not. *}
property CurrentRowSelected: Boolean
read GetCurrentRowSelected
write SetCurrentRowSelected;
{* The Items property is a TStringList of
TBookmarkStr *}
property Items[Index: Integer]: TBookmarkStr
read GetItem; default;
end;
