如何在WPF c#中绑定一个有Mousedown事件的键下边界

我有一个边框:

<Border x:Name="butborder1" BorderThickness="1" Grid.Row="0" CornerRadius="0,10,10,0" 
 BorderBrush="Black" Margin="0,98,33,0" Height="41" VerticalAlignment="Top" 
 HorizontalAlignment="Right" Width="87" IsEnabled="False" MouseUp="butborder1_MouseUp" 
 KeyDown="butborder1_KeyDown">

它有一个MouseUp事件:

private void butborder1_MouseUp(object sender, MouseButtonEventArgs e){
        butborder5.Visibility = Visibility.Visible;
        rotate.Visibility = Visibility.Visible;
        butborder4.Visibility = Visibility.Visible;
        image2.Visibility = Visibility.Visible;
        butborder1.Visibility = Visibility.Hidden;
        image4.Visibility = Visibility.Hidden;
        butborder2.Visibility = Visibility.Hidden;
        image3.Visibility = Visibility.Hidden;
        butborder3.Visibility = Visibility.Hidden;
        image1.Visibility = Visibility.Hidden;
        SetInput(true);
        butin(false);
        butborder4.IsEnabled = true;}

我想绑定一个keydown事件，但它不工作:

private void butborder1_KeyDown(object sender, KeyEventArgs e){
    if (e.Key == Key.Insert)
    {
        butborder1_MouseUp(null,null);
    }
}

简单:

我有一个边界，就像我的WPF表单上的按钮，它有一个鼠标up事件，工作完美，我的用户想按下一个键，而不是点击那个按钮，所以我应该给它一个KeyDown事件…但是KeyDown事件不能调用MouseUp事件…

你的问题很宽泛，所以试试这个。我认为这应该调用函数butborder1_MouseUp(null,null); 

private void butborder1_KeyDown(object sender, KeyEventArgs e){
    // This is not always true.
    //if (e.Key == Key.Insert)
    //{
        butborder1_MouseUp(null,null);
    //}
}
