Question

I’m not sure how to approach this: I want a TreeView that will display some simple data from a hierarchical data structure. As a basic example (In XML, cause it’s easy to type):

<Node text='Root'>     <Node text='Item 1'>         <Node text='Item 1.1' />     </Node>     <Node text='Item 2'/> </Node> 

The catch is that this could theoretically nest infinitely deep, so you can’t statically define x number of levels and be done with it. Is there a way to define a HierarchicalDataTemplate that can account for this kind of structure?

Answer 1

HeirarchicalDataTemplate is used exactly to solve this kind of issue. You can just use a simple template like bellow to achieve this.

  <HierarchicalDataTemplate DataType='Node' ItemsSource ='{Binding XPath=*}'>         <TextBlock Text='{Binding XPath=@text}' />     </HierarchicalDataTemplate>
