WPF 依賴屬性

依賴屬性，簡單的說，在WPF控制項應用過程中，界面上直接可以引用的屬性

如：<Button Content="aaa"></Button>

Content稱為Button的依賴屬性

當我們自定義控制項時，如何添加依賴屬性呢

1、添加屬性

        /// <summary>
        /// get or set the items
        /// </summary>
        public List<TitleListItemModel> TitleListItems
        {
            get
            {
                return (List<TitleListItemModel>) GetValue(TitleListItemsProperty)
            }
            set{SetValue(TitleListItemsProperty,value);};
        }

2、註冊屬性

        public static readonly DependencyProperty TitleListItemsProperty = DependencyProperty.Register("TitleListItems", typeof(List<TitleListItemModel>),
            typeof(TitleListControl),new PropertyMetadata(new List<TitleListItemModel>()));

然後在應用自定義控制項時，就能直接設置屬性了，例如：

TitleListItems屬性可以直接在界面上添加

        <wpfApplication6:TitleListControl VerticalAlignment="Center">
            <wpfApplication6:TitleListControl.TitleListItems>
                <wpfApplication6:TitleListItemModel Name="AAA" Text="aa"></wpfApplication6:TitleListItemModel>
                <wpfApplication6:TitleListItemModel Name="bb" Text="BB"></wpfApplication6:TitleListItemModel>
                <wpfApplication6:TitleListItemModel Name="ccc" Text="CC"></wpfApplication6:TitleListItemModel>
            </wpfApplication6:TitleListControl.TitleListItems>
        </wpfApplication6:TitleListControl>
