我正在制作一个 Windows 应用商店应用程序。在 XAML 主页中,我有一个 ListView,我正在尝试将其绑定到代码隐藏文件中的可观察集合。
但我看到的是一个空白屏幕。为什么列表没有填充?
编辑:
我正在制作一个应用程序以在 XAML 中显示某些 UI 控件的名称,稍后我将在列表的每一行上添加单击事件以转到显示该控件演示的新页面,这就是为什么我使用名称 Control 作为模型. 我正在制作自己的简单厨房水槽应用程序。
这是MainPage.xaml:
<ListView x:Name="listOfControls" ItemsSource="{Binding controlsDataSource}" SelectionChanged="listOfControls_SelectionChanged">
<ListView.ItemTemplate>
<DataTemplate>
<StackPanel>
<TextBlock Text="{Binding name}"></TextBlock>
<TextBlock Text="{Binding desc}"></TextBlock>
</StackPanel>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
这是MainPage.xaml.cs
注意:代码中使用的术语 Control 是我给模型类起的一个名称,它与 UI 控件无关。

protected override void OnNavigatedTo(NavigationEventArgs e)

void listOfControls_SelectionChanged(object sender, SelectionChangedEventArgs e)

}
}

namespace AllControls.Models
{
class Control
{
private String name{ get;set;}

public Control(String iName, String iDesc)
{
name = iName;
desc = iDesc;
}
}
}
