WPF中的弹出键绑定

Question

是否可以绑定在wpf弹出窗口中按下的键？

我这样尝试，但似乎没有效果：

<Popup.InputBindings>
   <KeyBinding Key="Escape" Command="Close" />
   <KeyBinding Key="Enter" Command="{Binding NewDateSelectedCommand}" />
</Popup.InputBindings>

Answer 1

您可以，必须将Focus（）设置为弹出窗口

<Popup x:Name="popup">
    <Popup.InputBindings>
       <KeyBinding Key="Escape" Command="Close" />
       <KeyBinding Key="Enter" Command="{Binding NewDateSelectedCommand}" />
    </Popup.InputBindings>
</Popup>

public void ShowPopup()
{
    this.popup.IsOpen = true;
    this.popup.Focus();
}
