WPF中的彈出鍵綁定

Question

是否可以綁定在wpf彈出窗口中按下的鍵？

我這樣嘗試，但似乎沒有效果：

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

Answer 1

您可以，必須將Focus（）設置為彈出窗口

<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();
}
