How to load TreeViewITem style from Resource Dictionary in wpf mvvm

In my TreeViewDictionary.xaml i have defined the style as below. Its a Resource Dictionary file for reuse. How do i refer this treeviewitem in view . When i refer it using ItemCcontainerStyle of TreeView, it throws below error :

<Treeview ItemContainerStyle="{StaticResource treeViewDictionary}"/>

An unhandled exception of type 'System.InvalidOperationException' occurred in WindowsBase.dll

Additional information: '{DependencyProperty.UnsetValue}' is not a valid value for property 'Margin'.
