WPF中的箭头键绑定问题 [英] Arrow Key Binding Problem in WPF

问题描述

大家好，

我有关于箭头键绑定到命令的问题。其他键工作正常。例如，下面的xaml代码，工作正常

Hi people,
I have a problem about arrow key binding to command. Other keys works fine. For example, the xaml code in below, works fine

<Window.InputBindings>
    <KeyBinding Command="{Binding Path=DenemeCommand}" Key="A" />
</Window.InputBindings>

但是遵循xaml代码doest not

But following xaml code doest not

<Window.InputBindings>
    <KeyBinding Command="{Binding Path=DenemeCommand}" Key="Left" />
</Window.InputBindings>

有在代码隐藏中是相同的stuation。



下面的代码工作正常

There is same stuation in codebehind.

Code in below works fine

var viewmodel = (ViewModels.ViewModelLocator)FindResource("Locator");
var gesture = new KeyGesture(Key.Delete);
var inputBinding = new InputBinding(viewmodel.MainViewModel.DenemeCommand, gesture);
InputBindings.Add(inputBinding);

此代码没有。

this code does not.

var viewmodel = (ViewModels.ViewModelLocator)FindResource("Locator");
 var gesture = new KeyGesture(Key.Left);
 var inputBinding = new InputBinding(viewmodel.MainViewModel.DenemeCommand, gesture);
 InputBindings.Add(inputBinding);

我不明白为什么会这样。不仅是左键。所有箭头键（右，下等）都不会触发命令执行。



提前谢谢。

I can not understand why this happen. Not only left key. All arrow key(Right,Down etc.) does not trigger the command execution.

Thanks in advance.
