.net - 将 CollectionViewSource 绑定(bind)到 ObservableCollection

Question

无法绑定(bind) CollectionViewSource

DocProps 是公共(public)属性(property)

public ObservableCollection<DocProp> DocProps1

DataContext 是自我

DataContext="{Binding RelativeSource={RelativeSource self}}"

这有效

<ListBox Grid.Row="0" Grid.Column="0" ItemsSource="{Binding Path=DocProps1}">

我无法连接 CollectionViewSource 进行排序
这甚至没有得到 DocProps1

    <ListBox Grid.Row="0" Grid.Column="0">
        <ListBox.ItemsSource>
            <Binding>
                <Binding.Source>
                    <CollectionViewSource Source="{Binding Path=DocProps1}">
                        <CollectionViewSource.SortDescriptions>
                            <scm:SortDescription PropertyName="Name" />
                        </CollectionViewSource.SortDescriptions>
                    </CollectionViewSource>
                </Binding.Source>
            </Binding>
        </ListBox.ItemsSource>

如何将 CollectionViewSource 绑定(bind)到公共(public)属性？

谢谢

Answer 1

它将以这种方式工作:

<ListBox ItemsSource="{Binding}">
  <ListBox.DataContext>
    <CollectionViewSource Source="{Binding Path=DocProps1}">
    </CollectionViewSource>
  </ListBox.DataContext>    
</ListBox>

本文 XAML Binding to a CollectionViewSource property on a ViewModel对这种行为有一些解释
