WPF 依赖属性

依赖属性,简单的说,在WPF控件应用过程中,界面上直接可以引用的属性

如:<Button Content="aaa"></Button>

Content称为Button的依赖属性

当我们自定义控件时,如何添加依赖属性呢

1、添加属性

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

2、注册属性

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

然后在应用自定义控件时,就能直接设置属性了,例如:

TitleListItems属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>
