Question

I’ve generated an XDocument at code behind as below:

<Root>
  <Pubs>
    <Book id='A123'>
      <Author state='AS'>Moreno</Author>
    </Book>
    <Book id='B456'>
      <Author state='BS'>Gazit</Author>
    </Book>
  </Pubs>
</Root>

and want to bind this to a Treeview control in WPF application to have something like this:

+ Pubs              //Pubs Element Name
  + A123            //Book Element Attribute Value
    + Moreno        //Author Element Inner text
  + B456
    + Gazit

so, what is the best solution?

Answer 1

This Is the Answer:

For each Level of TreeView we must define a specificHierarchicalDataTemplate in TreeView.Resources with:

1. DataType = element name
2. ItemsSource = binding child name

for example as below:

  <TreeView Name="treeView2"   ItemsSource="{Binding Path=Root.Elements}">
            <TreeView.Resources>

                <HierarchicalDataTemplate DataType="Book" ItemsSource="{Binding Path=Elements}" x:Key="template1">
                        <TextBlock Text="{Binding Path='Attribute[id].Value'}"/>
                </HierarchicalDataTemplate>

                <HierarchicalDataTemplate DataType="Pubs" ItemsSource="{Binding Path=Elements}" x:Key="template2">
                        <TextBlock Text="{Binding Path='Name'}"/>
                </HierarchicalDataTemplate>

                <HierarchicalDataTemplate DataType="Author" x:Key="template3">
                        <TextBlock Text="{Binding Path='Attribute[state].Value'}"/>
                </HierarchicalDataTemplate>

        </TreeView.Resources>
    </TreeView>

and everything is ok!
