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>
