Tip Rating (6):  
     


{
 In the "Object Inspector" set your DBGrid's Option for dgMultiSelect = True.
 The Grid_Edit function calls for each selected DBGrid-Row a data-processing
 function.
 Return value is the number of processed rows.

 Im Objektinspektor unter Options des DBGrids die Option "dgMultiSelect"
 auf TRUE setzen.
 Ruft zu jeder markierten DBGrid-Zeile eine Bearbeitungs-Funktion auf
 Rückgabewert = Anzahl bearbeiteter Zeilen
}

function TForm1.Grid_Edit(dbgIn: TDBGrid; qryIn: TQuery): Longint;
  // declared in the private section
  // als private deklariert
begin
  
Result := 0;
  with dbgIn.DataSource.DataSet do
  begin
    
First;
    DisableControls;
    try
      while not 
EOF do
      begin
        if 
(dbgIn.SelectedRows.CurrentRowSelected = True) then
        begin
          
{ +++ Call here the data-processing function +++
          
           +++ HIER DIE BEARBEITUNGS_FKT AUFRUFEN +++
           zb. iValue := qryIn.FieldByName('FELDNAME').AsInteger;
           und so weiter...
          }
          
Inc(Result);
        end;
        Next;
      end;
    finally
      
EnableControls;
    end;
  end;
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
  
Form1.Caption := 'Processed: ' + IntToStr(Grid_Edit(DBGrid1, Query1));
end;
