示例

以下示例演示如何实现与 一起Frame响应 BrowseHome 命令的代码。

<Window
  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
  x:Class="SDKSample.BrowseHome">

<!-- NavigationCommands.BrowseHome -->
<MenuItem Command="NavigationCommands.BrowseHome">
  <MenuItem.CommandBindings>
    <!-- NavigationCommands.BrowseHome Binding-->
    <CommandBinding
      Command="NavigationCommands.BrowseHome"
      CanExecute="navigationCommandBrowseHome_CanExecute"
      Executed="navigationCommandBrowseHome_Executed" />
  </MenuItem.CommandBindings>
</MenuItem>

<Frame Name="frame" NavigationUIVisibility="Hidden" Source="Page1.xaml" />

</Window>

using System.Windows;
using System.Windows.Input;

namespace SDKSample
{
    public partial class BrowseHome : Window
    {
        public BrowseHome()
        {
            InitializeComponent();
        }

        void navigationCommandBrowseHome_CanExecute(object sender, CanExecuteRoutedEventArgs e)
        {
            // Can always navigate home
            e.CanExecute = true;
        }

        void navigationCommandBrowseHome_Executed(object target, ExecutedRoutedEventArgs e)
        {
            // Implement custom BrowseHome handling code
        }
    }
}


Namespace SDKSample
    Partial Public Class BrowseHome
        Inherits Window
        Public Sub New()
            InitializeComponent()
        End Sub

        Private Sub navigationCommandBrowseHome_CanExecute(ByVal sender As Object, ByVal e As CanExecuteRoutedEventArgs)
            ' Can always navigate home
            e.CanExecute = True
        End Sub

        Private Sub navigationCommandBrowseHome_Executed(ByVal target As Object, ByVal e As ExecutedRoutedEventArgs)
            ' Implement custom BrowseHome handling code
        End Sub
    End Class
End Namespace

注解

此命令指示要导航回家的意图。

在任何给定的 WPF 类上，都没有用于响应 BrowseHome 命令的实现。 因此，需要提供适当的实现，如示例中所示。

XAML 属性用法

<object property="NavigationCommands.BrowseHome"/>
