后退按钮在 XAML/W8 中不起作用 [英] Back button not working in XAML / W8

问题描述

我的页面上有以下按钮:

I have the following button on my page:

 <AppBarButton Grid.Column="0" x:Name="backButton" Icon="Back" Margin="10,26,0,-1"
                      Command="{Binding NavigationHelper.GoBackCommand, ElementName=pageRoot}" 
                      IsEnabled="True"
                      Visibility="Visible"
                      Foreground="Green"

                      AutomationProperties.Name="Back"
                      AutomationProperties.AutomationId="BackButton"
                      AutomationProperties.ItemType="Navigation Button" Grid.Row="1" Grid.RowSpan="2" VerticalAlignment="Stretch"
                      />

按钮出现，但点击它什么也不做.这被放置在应用程序的两页中的第二页.我按照 NavigatonHelper.cs 中的说明将它连接到我的第二页，但在第一页中没有做任何特别的事情.我错过了什么?

The button appears but clicking it does nothing. This was placed on the second of two pages in the application. I followed the instructions in NavigatonHelper.cs to get it wired up to my second page, but haven't done anything special in the first. What am I missing?

我什至尝试将 Click 属性绑定到自定义函数:

I even tried tying the Click property to a custom function:

 public void ClickGoBack(object sender, RoutedEventArgs routedEventArgs) {
        this.Frame.Navigate(typeof(HubPage));
    }

但是当我点击按钮时，它甚至从未被击中.

But this never even got hit when I clicked the button.

推荐答案

XAML 中与按钮重叠的顶部网格后面放了一些东西 - 直到现在我才理解自然顺序"的概念.感谢大家的帮助！

Something was put after the top grid in the XAML that overlapped the button - I didn't understand the concept of "natural order" until now. Thanks for the help everyone!
