示例

以下示例演示如何实现与 一起FlowDocumentPageViewer响应 Search 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.Search">

  <Window.CommandBindings>
    <CommandBinding
      Command="NavigationCommands.Search"
      CanExecute="navigationCommandSearch_CanExecute"
      Executed="navigationCommandSearch_Executed" />
  </Window.CommandBindings>

<!-- NavigationCommands.Search -->
<MenuItem Command="NavigationCommands.Search" />

<FlowDocumentPageViewer Name="flowDocumentPageViewer">
  <FlowDocument>
    <!-- Document Content-->

</Window>

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

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

        void navigationCommandSearch_CanExecute(object sender, CanExecuteRoutedEventArgs e)
        {
            // Can search of there is a document
            e.CanExecute = (this.flowDocumentPageViewer.Document != null);
        }

        void navigationCommandSearch_Executed(object target, ExecutedRoutedEventArgs e)
        {
            // Implement custom Search handling code
        }
    }
}


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

        Private Sub navigationCommandSearch_CanExecute(ByVal sender As Object, ByVal e As CanExecuteRoutedEventArgs)
            ' Can search of there is a document
            e.CanExecute = (Me.flowDocumentPageViewer.Document IsNot Nothing)
        End Sub

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

注解

此命令指示要搜索的意图。

在任何给定的 WPF 类上，都没有用于响应 Search 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.Search"/>
