Question

I am looking for a way to draw dotted lines to connect nodes in a wpf TreeView. The problem seems to be that i am using HierarchicalDataTemplate instead of populating the TreeView with TreeViewItems.

I have found this post:

Witch solves it great in the case when populating it TreeViewItems but my question is, how would i solve it with HierarchicalDataTemplate?

My template look something like this:

<HierarchicalDataTemplate DataType = "{x:Type Team}" ItemsSource ="{Binding Path=Players">
   <TextBlock Text="{Binding Path=Name}" />
</HierarchicalDataTemplate>

<DataTemplate  DataType = "{x:Type Player}">
   <TextBlock Text="{Binding Path=Name}" />
</DataTemplate >

Any solution or good hints on how to solve the problem?

The easiest ways, in my opinion, was to add the code in the itemstyle

<HierarchicalDataTemplate.ItemContainerStyle>
   <Style TargetType="{x:Type TreeViewItem}">
      <!--your style-->
   </Style>
</HierarchicalDataTemplate.ItemContainerStyle>
