CheckBox 樣式和範本
本主題說明 CheckBox 控制項的樣式和範本。 您可以修改預設 ControlTemplate，為控制項提供唯一的外觀。 如需詳細資訊，請參閱建立控制項的範本。
CheckBox 組件
CheckBox 控制項沒有任何具名組件。
CheckBox 狀態
下表列出 CheckBox 控制項的視覺狀態。
| VisualState 名稱 | VisualStateGroup 名稱 | 描述 |
|---|---|---|
| Normal | CommonStates | 預設狀態。 |
| MouseOver | CommonStates | 滑鼠指標移到控制項上。 |
| 按下 | CommonStates | 已按下控制項。 |
| 已停用 | CommonStates | 已停用控制項。 |
| 焦點 | FocusStates | 控制項已取得焦點。 |
| 未取得焦點 | FocusStates | 控制項未取得焦點。 |
| 已選取 | CheckStates | IsChecked 為 true。 |
| 未選取 | CheckStates | IsChecked 為 false。 |
| 未決 | CheckStates | IsThreeState 為 true，且 IsChecked 為 null。 |
| 有效 | ValidationStates | 控制項會使用 Validation 類別，且 Validation.HasError 附加屬性為 false。 |
| InvalidUnfocused | ValidationStates | Validation.HasError 附加屬性為具有焦點控制項的 true。 |
| InvalidFocused | ValidationStates | Validation.HasError 附加屬性為不具有焦點控制項的 true。 |
