我在DBgrid中用多重選擇的方式將值選出來再塞入至另一個的dbgrid1中 要如何知道dbgrid中篩選出來值的某一個欄位(只需要知道學號這個欄位值)    < >< >

Hi tinny,

procedure TForm1.Button3Click(Sender: TObject);
var
  i: Integer;
  SavePlace: TBookmark;
begin
  Memo1.Lines.Clear;
  if DBGrid2.SelectedRows.Count > 0 then
    begin
      SavePlace := DBGrid2.DataSource.DataSet.GetBookmark;
      try
        for i:=0 to DBGrid2.SelectedRows.Count-1 do
          begin
            DBGrid2.DataSource.DataSet.GotoBookmark(pointer(DBGrid2.SelectedRows.Items[i]));
            Memo1.Lines.Add(DBGrid2.DataSource.DataSet.FieldByName('id').AsString); // all the rows been selected
          end;
      finally
        DBGrid2.DataSource.DataSet.GotoBookmark(SavePlace);
        DBGrid2.DataSource.DataSet.FreeBookmark(SavePlace);
      end;
    end;
end;

For more detail information and sample codes, you can search the help on delphi with key word SelectedRows, GetBookmark, GotoBookmark, FreeBookmark... ---------------------------------- 小弟才疏學淺，若有謬誤尚請不吝指教 ----------------------------------
