取得或設定值，表示核取方塊是否有 Flat 或 Normal 的 ButtonState。

public:
 property bool ThreeDCheckBoxes { bool get(); void set(bool value); };

public bool ThreeDCheckBoxes { get; set; }

member this.ThreeDCheckBoxes : bool with get, set

Public Property ThreeDCheckBoxes As Boolean

屬性值

如果核取方塊具有平面外觀，則為 true，否則為 false。 預設為 true。

範例

下列程式碼範例示範如何藉由設定 CheckOnClick 、 SelectionMode 和 ThreeDCheckBoxes 屬性來初始化 CheckedListBox 控制項。 此範例會以 CheckedListBox 控制項填入 ，並將 設定 DisplayMember 為 Control.Name 控制項的 屬性。

若要執行此範例，請將下列程式碼貼到包含 CheckedListBox 具名 CheckedListBox1 的表單中，並從表單的建構函式或 Load 方法呼叫 InitializeCheckListBox 方法。

   // This method initializes CheckedListBox1 with a list of all 
   // the controls on the form. It sets the selection mode
   // to single selection and allows selection with a single click.
   // It adds itself to the list before adding itself to the form.
internal:
   System::Windows::Forms::CheckedListBox^ CheckedListBox1;

private:
   void InitializeCheckedListBox()
   {
      this->CheckedListBox1 = gcnew CheckedListBox;
      this->CheckedListBox1->Location = System::Drawing::Point( 40, 90 );
      this->CheckedListBox1->CheckOnClick = true;
      this->CheckedListBox1->Name = "CheckedListBox1";
      this->CheckedListBox1->Size = System::Drawing::Size( 120, 94 );
      this->CheckedListBox1->TabIndex = 1;
      this->CheckedListBox1->SelectionMode = SelectionMode::One;
      this->CheckedListBox1->ThreeDCheckBoxes = true;
      System::Collections::IEnumerator^ myEnum = this->Controls->GetEnumerator();
      while ( myEnum->MoveNext() )
      {
         Control^ aControl = safe_cast<Control^>(myEnum->Current);
         this->CheckedListBox1->Items->Add( aControl, false );
      }

      this->CheckedListBox1->DisplayMember = "Name";
      this->CheckedListBox1->Items->Add( CheckedListBox1 );
      this->Controls->Add( this->CheckedListBox1 );
   }

// the controls on the form. It sets the selection mode
