Adding context menu to tree view by XAML only

Question

Trying to add a context menu to a TreeView with just xaml code.

Tv Show
- Season 1
- Season n

The context menu should only show when I right click a Season node.

Is that possible? I know how to solve it with code behind, but I'd like to learn to use WPF as it is intended. I have trouble finding out if I should be able to solve this with using only xaml.

Current xaml:

 <TreeView Grid.Row="1" Grid.Column="0" ItemsSource="{Binding TvShows}" x:Name="TvShowsTreeView" SelectedItemChanged="TvShowsTreeViewOnSelectedItemChanged"> <TreeView.ItemTemplate> <HierarchicalDataTemplate DataType="tvShows:TvShow" ItemsSource="{Binding Seasons}"> <TextBlock Text="{Binding Name}" /> </HierarchicalDataTemplate> </TreeView.ItemTemplate> </TreeView>

How are you constructing the tree? by using HierarchicalDataTemplate? post your current XAML. — Fede

@HighCore, added xaml. Also have some "try" with the context menu, but it didn't lead to much yet, so I left it out for now, hoping on something that does make sense from SO :) — bas

Try using the ItemTemplate property of HierarchicalDataTemplate. It should look like this:

 <HierarchicalDataTemplate DataType="tvShows:TvShow" ItemsSource="{Binding Seasons}"> <TextBlock Text="{Binding Name}" /> <HierarchicalDataTemplate.ItemTemplate> <DataTemplate DataType="TypeOfSeasonInYourApplication"> <TextBlock Text="{Binding Name}"> <TextBlock.ContextMenu> <ContextMenu> <!-- Place MenuItems here --> </ContextMenu> </TextBlock.ContextMenu> </TextBlock> </DataTemplate> </HierarchicalDataTemplate.ItemTemplate> </HierarchicalDataTemplate>

I actually didn't test that myself so please let me know if that works or not.

Nope, not quite: Property 'VisualTree' does not support values of type 'DataTemplate'.
Hmm, strange, that used to work in my case. By the error message you wrote I can only advice you to doublecheck if you placed DataTemplate inside of ItemTemplate property and not in HierarchicalDataTemplate itself (that wouldn't work for sure).
