取得或設定核取記號在 CheckBox 控制項上的水平和垂直對齊情形。

 property System::Drawing::ContentAlignment CheckAlign { System::Drawing::ContentAlignment get(); void set(System::Drawing::ContentAlignment value); };

[System.ComponentModel.Bindable(true)]
public System.Drawing.ContentAlignment CheckAlign { get; set; }

[<System.ComponentModel.Bindable(true)>]
member this.CheckAlign : System.Drawing.ContentAlignment with get, set

Public Property CheckAlign As ContentAlignment

其中一個 ContentAlignment 值。 預設值是 MiddleLeft。

屬性

BindableAttribute

例外狀況

InvalidEnumArgumentException

所指派的值不是其中一個 ContentAlignment 列舉值。

範例

下列程式碼範例會顯示標籤中三個屬性的值。 屬性 ThreeState 會在 和 false 之間 true 替代，並以 控制項的替代點選，以及 CheckAlign 的 MiddleRight 和 MiddleLeft 值 ContentAlignment 之間的替代專案。 本範例示範屬性值在屬性變更時 ThreeState 如何變更，並檢查控制項。 此範例要求 CheckBox 在表單上具現化 和 LabelButton ，而且標籤夠大，足以顯示三行文字，以及命名空間的 System.Drawing 參考。 這個程式碼應該在 Click 控制項的事件處理常式中呼叫。
