Question

我无法从后面的代码中设置InputGestureText。快捷键工作正常但键字符串不会与菜单项一起显示。

下面提到了XAML和C＃代码。

环境： VS2012＆amp; .NET Framework 4.5

知道我缺少什么吗？

//********************
//XAML

        <DockPanel Grid.Row="0" Grid.ColumnSpan="2">
            <Menu DockPanel.Dock="Top" Background="White">
                <MenuItem x:Name="mnuFile" Header="_File">
                    <MenuItem x:Name="mnuFileNew" Header="_New..." />
                    <MenuItem x:Name="mnuFileOpen" Header="_Open for Editing..." />
                    <Separator />
                    <MenuItem x:Name="mnuFileExit" Header="E_xit" />
                </MenuItem>
            </Menu>
        </DockPanel>

public MainWindow()

    InitializeComponent();

    //File > New
    mnuFileNew.Click += mnuFileNew_Click;
    RoutedCommand cmdNewReport = new RoutedCommand();
    cmdNewReport.InputGestures.Add(new KeyGesture(Key.N, ModifierKeys.Control | ModifierKeys.Shift, "Ctrl+Shift+N"));
    CommandBindings.Add(new CommandBinding(cmdNewReport, mnuFileNew_Click));
}

void mnuFileNew_Click(object sender, RoutedEventArgs e)
{
    MessageBox.Show("New Report not implemented!", this.Title, MessageBoxButton.OK, MessageBoxImage.Information);
}

如果您想使用后面的代码，请尝试使用此代码来显示快捷方式：

mnuFileNew.Click += mnuFileNew_Click;
RoutedCommand cmdNewReport = new RoutedCommand();

var keyGesture = new KeyGesture(Key.N, ModifierKeys.Control | ModifierKeys.Shift, "Ctrl+Shift+N");
cmdNewReport.InputGestures.Add(keyGesture);
mnuFileNew.InputGestureText = keyGesture.DisplayString;

CommandBindings.Add(new CommandBinding(cmdNewReport, mnuFileNew_Click));

无法从后面的代码设置InputGestureText
