我的数据结构如下所示:
public class MyDataContext
{
public ObservableCollection<Car> CarList {set; get;}
}
public class Car
{
public Driver CarDriver {set; get;} // implements INotifyPropertyChanged (not shown here to keep it short)
public string Color {set; get;} // implements INotifyPropertyChanged (not shown here to keep it short)
public string Brand {set; get;} // implements INotifyPropertyChanged (not shown here to keep it short)
}
public class Driver
{
public string Name {set; get;}
public string Nationality {set; get;}
}
我正在将 CarList 绑定到 XAML 中的列表视图,并且我想为汽车和驱动程序创建数据模板。我的用户控件如下所示:
<UserControl.Resources>
<DataTemplate DataType="{x:Type local:Car}>
<StackPanel>
<UserControl DataContext="{Binding CarDriver}"/>
<TextBlock Text="{Binding Color}"/>
<TextBlock Text="{Binding Brand}"/>
</StackPanel>
</DataTemplate>
<DataDataTemplate DataType="{x:Type local:Driver}>
<StackPanel>
<TextBlock Text="{Binding Name}"/>
<TextBlock Text="{Binding Nationality}"/>
</StackPanel>
</DataTemplate>
</UserControl.Resources>
<ListView ItemsSource="{Binding CarList}"/>
问题是列表视图不显示汽车驱动程序的信息。我怀疑我的台词
<UserControl DataContext="{Binding CarDriver}"/>
不正确,但我不确定要放什么...?
你应该放一个这样的ContentControl
:
<ContentControl Content="{Binding CarDriver}">
一切都会正常工作。 如果没有 - 尝试将Driver
的DataTemplate
放在DataTemplate
之上,以便Car
