WPF: Add ContextMenu to TreeView
提问by bas
For a second there I was proud that I finally managed to add a ContextMenuto a leaf in my TreeView, but then I realized it pops up on the wrong node.
有那么一瞬间，我很自豪我终于成功地ContextMenu在我的TreeView.
My XAML:
我的 XAML：
<TreeView
Grid.Row="1"
Grid.Column="0"
x:Name="TvShowsTreeView"
ItemsSource="{Binding TvShows}"
SelectedItemChanged="TvShowsTreeViewOnSelectedItemChanged">
<!-- Season template -->
<TreeView.ItemTemplate>
<HierarchicalDataTemplate ItemsSource="{Binding Seasons}">
<TextBlock Text="{Binding Name}">
<TextBlock.ContextMenu>
<ContextMenu>
<MenuItem Header="Hide"></MenuItem>
</ContextMenu>
</TextBlock.ContextMenu>
</TextBlock>
</HierarchicalDataTemplate>
</TreeView.ItemTemplate>
</TreeView>
When I run this, I get a context menu on the TvShows, not on the Seasons.
当我运行它时，我TvShows在Seasons.
I am close, right? :) Who can help me further here?
我很接近，对吧？:) 谁能帮我更进一步？

The correct XAML should be like this:
正确的 XAML 应该是这样的：
<TreeView
Grid.Row="1"
Grid.Column="0"
x:Name="TvShowsTreeView"
ItemsSource="{Binding TvShows}"
SelectedItemChanged="TvShowsTreeViewOnSelectedItemChanged">
<!-- TvShows template -->
<TreeView.ItemTemplate>
<HierarchicalDataTemplate ItemsSource="{Binding Seasons}">
<TextBlock Text="{Binding Name}" />
<!-- Seasons template -->
<HierarchicalDataTemplate.ItemTemplate>
<HierarchicalDataTemplate>
<TextBlock Text="{Binding Name}">
<TextBlock.ContextMenu>
<ContextMenu>
<MenuItem Header="Hide"></MenuItem>
</ContextMenu>
</TextBlock.ContextMenu>
</TextBlock>
</HierarchicalDataTemplate>
</HierarchicalDataTemplate.ItemTemplate>
</HierarchicalDataTemplate>
</TreeView.ItemTemplate>
</TreeView>
The additional HierarchicalDataTemplate specifies the template for Seasons, which itself does not need to bind ItemSource because it does not contain nodes.
附加的 HierarchicalDataTemplate 指定了 Seasons 的模板，它本身不需要绑定 ItemSource，因为它不包含节点。
