GridView ItemClick未检测到？ [英] GridView ItemClick not detected?

问题描述

大家好，

我正在使用Template 10 Hamburger开发一个UWP应用程序。我创建了一个GridView并试图添加项目点击属性，但是没有检测到该事件，并且从不调用事件处理程序。

I am developing a UWP application, using Template 10 Hamburger. I created a GridView and tried to add item click property, but the event is not detected, and the event handler is never called.

源代码如下：

BookViewModel.cs：

BookViewModel.cs:

 public void NavigateToDetails(string url)
        {
            NavigationService.Navigate(typeof(Views.DetailPage), url);
            
        }


        public void BookGroups_OnItemClick(object sender, ItemClickEventArgs e)
        {

            var bookHeader = (BookGroup)e.ClickedItem;
            NavigateToDetails(bookHeader.url);
            

        }

Book.xaml：

Book.xaml:

<Page.DataContext>
        <vm:BookViewModel x:Name="ViewModel" />
    </Page.DataContext>
    
    <Page.Resources>
        <CollectionViewSource x:Key="BookViewSource"                           
                              IsSourceGrouped="True"                           
                              Source="{Binding BookGroups}"                           
                              ItemsPath="url" />
    </Page.Resources>





    <GridView 
              Grid.Row="1"  
              Name="GridView1"
              Padding="18"           
              ItemsSource="{Binding Source={StaticResource BookViewSource}}"           
              IsItemClickEnabled="True" 
              ItemClick="{x:Bind ViewModel.BookGroups_OnItemClick}"
                       
              >
        
        <GridView.ItemTemplate>
            <DataTemplate>
                <Grid Width="250" Height="250">
                    <Border VerticalAlignment="Bottom" Background="#AA000000">
                        <TextBlock Text="{Binding name}" Margin="12" Foreground="White"/>
                    </Border>
                </Grid>

            </DataTemplate>
        </GridView.ItemTemplate>
        
       


        <GridView.GroupStyle>
            <GroupStyle>
                <GroupStyle.HeaderTemplate>
                    <DataTemplate>
                        <TextBlock Text="{Binding name}" Margin="-12,0,0,0"/>
                    </DataTemplate>
                </GroupStyle.HeaderTemplate>
            </GroupStyle>
        </GridView.GroupStyle>
    </GridView>

感谢您的帮助。

推荐答案

看起来你的DataTemplate中的Grid没有对事件做出反应。尝试给它一个背景（甚至透明就可以），或者将它设置为
true 的IsHitTestVisible。

It looks like the Grid in your DataTemplate is not reacting to events. Try giving it a Background (even Transparent is OK), or set it IsHitTestVisible to true.
