如何在cxGrid未绑定模式下隐藏行

Question

如何在cxGrid未绑定模式下隐藏行？

已经好几个小时了，我无法理解。我用Google搜索并失败了。

我刚刚在unbound mode创建了一个带有网格的示例应用，并使用了OnFilterRecord在其recommendation中建议的DevExpress，它运行正常。

您可以看到我的测试代码：

type
  TForm1 = class(TForm)
    testLevel: TcxGridLevel;
    testGrid: TcxGrid;
    testView: TcxGridTableView;
    testViewColumn1: TcxGridColumn;
    testViewColumn2: TcxGridColumn;
    procedure FormCreate(Sender: TObject);
    procedure tviewDataControllerFilterRecord(
      ADataController: TcxCustomDataController; ARecordIndex: Integer;
      var Accept: Boolean);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.FormCreate(Sender: TObject);
begin
  testView.DataController.RecordCount := testView.DataController.RecordCount + 1;
  testView.DataController.Values[testView.DataController.RecordCount - 1,0] := 'foo';
  testView.DataController.Values[testView.DataController.RecordCount - 1,1] := 'bar';

  testView.DataController.RecordCount := testView.DataController.RecordCount + 1;
  testView.DataController.Values[testView.DataController.RecordCount - 1,0] := 'foo2';
  testView.DataController.Values[testView.DataController.RecordCount - 1,1] := 'bar2';
end;

procedure TForm1.tviewDataControllerFilterRecord(
  ADataController: TcxCustomDataController; ARecordIndex: Integer;
  var Accept: Boolean);
begin
  Accept := (testView.DataController.Values[ARecordIndex,0] <> 'foo');
end;

结果：
