Question

我正在将一些Win RT代码移植到UWP。其中一个不能按预期工作的页面是HubPage。

我在HubSection HeaderTemplate中有一个按钮，应该替换“查看更多”HyperLink。我的模板中的按钮出现但不接受点击。

文档声明我应该能够用我自己的模板替换“看到更多”超链接，我相信这是我的代码正在做但不起作用。

如果我试图替换IsHeaderInteractive HubSection，我不确定HeaderTemplate应该是什么价值。任何有用的帮助

Answer 1

这是设计的。您可以自己制作自己的HubSection按钮。例如，如下所示：

<HubSection>
     <DataTemplate>
          <StackPanel>
               <Button Content="Header" Click="Button_Click" Margin="0 0 0 10"></Button>
               <TextBlock Text="here is content."></TextBlock>
          </StackPanel>
    </DataTemplate>
</HubSection>
