public:
property bool Disabled { bool get(); void set(bool value); };public bool Disabled { get; set; }[System.ComponentModel.TypeConverter(typeof(System.Web.UI.MinimizableAttributeTypeConverter))]
public bool Disabled { get; set; }member this.Disabled : bool with get, set[<System.ComponentModel.TypeConverter(typeof(System.Web.UI.MinimizableAttributeTypeConverter))>]

備註
在瀏覽器中，已停用的元素或控制項是唯讀的，但有下列新增的限制：其值不會以表單提交、元素或控制項無法接收焦點，而且在流覽檔時會透過 Tabbing 略過專案或控制項。
