WPF: TreeView unable to apply Hierachical template and style at the same time

Here is what I want to do:

<TreeView>
 <TreeView.Resources>
                <Style TargetType="TreeViewItem" >
                    <Setter Property="dz:VirtualListItemBase.AutoLoad" Value="true" />
                </Style>
            </TreeView.Reso开发者_如何学运维urces>
            <TreeView.ItemTemplate>
                <HierarchicalDataTemplate ItemsSource="{Binding Data.Nodes}" >
                    <Label  Grid.Column="1"  Grid.Row="0"  Content="{Binding Data.Name}" dz:VirtualListItemBase.AutoLoad="true" />
                </HierarchicalDataTemplate>
            </TreeView.ItemTemplate>

The style part never gets applied. The HierachicalDataTemplate seems to override the initial style. I cannot use the type to apply the template since multiple types are involved. Any ideas?

Thanks

DataTemplate has higher precedence over Style. Try moving the DataTemplate into the Style as:

 <Style TargetType="TreeViewItem" > 
   <Setter Property="dz:VirtualListItemBase.AutoLoad" Value="true" />
   <Setter Property="ItemTemplate">
      <Setter.Value>
         <HierarchicalDataTemplate ...
         </HierarchicalDataTemplate> 
      </Setter.Value>
    </Setter>
 </Style>
