/UserControl此语法表达式对于Blend 比较友好。02—数据绑定这将自动将控件上的依赖项属性绑定到ViewModel上的属性。常规约定TextBox x:NameFirstName /将导致TextBox的“Text”属性绑定到ViewModel的“FirstName”属性。明确的写法TextBox Text{Binding PathFirstName, ModeTwoWay} /这是绑定属性的正常方式。03—项目实例前台XAML文件Window x:ClassWpfApp8.StartViewxmlnshttp://schemas.microsoft.com/winfx/2006/xaml/presentationxmlns:xhttp://schemas.microsoft.com/winfx/2006/xamlxmlns:dhttp://schemas.microsoft.com/expression/blend/2008xmlns:mchttp://schemas.openxmlformats.org/markup-compatibility/2006xmlns:calhttp://www.caliburnproject.org xmlns:localclr-namespace:WpfApp8mc:IgnorabledTitleStartView Height300 Width600 WindowStartupLocationCenterScreenStackPanelTextBox NameTextContent/Button x:NametestBtn ContenttestBtn BackgroundLightCyan/ListBox NameListBoxItems MinHeight230 BackgroundLightGraycal:Message.Attach[Event SelectionChanged] [Action ListBoxItems_SelectionChanged($source,$eventArgs)];[Event MouseUp][ListBoxItems_MouseUp($source,$eventArgs)] //StackPanel
