定义一个控件 继承一下UserControl namespace LeakDetection.CombustibleGasMonitoring.Pages.FirstGradePage.Views { public partial class BorderCheck : UserControl { public Boolean IsChecked { get { return (Boolean)GetValue(IsCheckedProperty); } set { SetValue(IsCheckedProperty, value); } } public static DependencyProperty IsCheckedProperty = DependencyProperty.Register("IsChecked", typeof(Boolean), typeof(BorderCheck), new PropertyMetadata(new PropertyChangedCallback(OnIsCheckedPropertyChanged))); private static void OnIsCheckedPropertyChanged(DependencyObject sender, DependencyPropertyChangedEventArgs e) { BorderCheck bc = sender as BorderCheck; if ((Boolean)e.NewValue == (Boolean)e.OldValue) { return; } if (bc.IsChecked) { bc.Bd.BorderThickness = new Thickness(10,10,10,10); } else { bc.Bd.BorderThickness = new Thickness(0); } } public BorderCheck() { InitializeComponent(); this.MouseEnter += delegate { this.Cursor = Cursors.Hand; }; this.MouseLeave += delegate { this.Cursor = Cursors.Arrow; }; } } }找个地方用它 事件以及操作都在这里了 namespace LeakDetection.CombustibleGasMonitoring.Pages.FirstGradePage.Views { public enum Grade { ONE = 0, TWO = 1 } /// /// FirstGradePageView.xaml 的交互逻辑 /// public partial class FirstGradePageView : Page { public FirstGradePageView() { InitializeComponent();
