将SHIFT + Delete KeyGesture分配给DevExpress条形项WPF

Question

不能将SHIFT + Delete KeyGesture分配给WPF中的DevExpress条项。对此有任何限制，还是我做错了？  <dxb:BarButtonItem
x:Name="btnDelete"
Command="{Binding BtnDelete_Command}"
CommandParameter="{Binding ElementName=view}"
KeyGesture="SHIFT+Delete"
Content="Delete" />

这是我尝试过的代码：

    <dxb:BarManager>
        <dxb:BarManager.Items>
            <dxb:BarButtonItem x:Name="btnDelete" Command="{Binding BtnDelete_Command}" CommandParameter="{Binding ElementName=view}" KeyGesture="SHIFT+Delete" Content="Delete" />
        </dxb:BarManager.Items>
        <dxb:BarManager.Bars>
            <dxb:Bar>
                <dxb:Bar.ItemLinks>
                    <dxb:BarButtonItemLink BarItemName="btnDelete"/>
                </dxb:Bar.ItemLinks>
            </dxb:Bar>
        </dxb:BarManager.Bars>
        <StackPanel>
            <Button Content="sdgsdg" />
            <TextBox x:Name="view"/>
        </StackPanel>
    </dxb:BarManager>



public partial class MainWindow : Window {
    public ICommand BtnDelete_Command { get; set; }
    public MainWindow() {
        BtnDelete_Command = new MyCommand();
        DataContext = this;
        InitializeComponent();
    }
}

public class MyCommand : ICommand {
    public bool CanExecute(object parameter) {
        return true;
    }

    public event EventHandler CanExecuteChanged {
        add { CommandManager.RequerySuggested += value; }
        remove { CommandManager.RequerySuggested -= value; }
    }

    public void Execute(object parameter) {
        MessageBox.Show(parameter.GetType().ToString());
    }
}

这里运作正常。如果编辑器未聚焦，则执行该命令。如果编辑器是聚焦的，它自己处理这个键组合，因此不执行命令。
