C-sharp

private void SolutionTree_SelectedItemChanged(object sender, RoutedPropertyChangedEventArgs<object> e){    TreeViewItem SelectedItem = SolutionTree.SelectedItem as TreeViewItem;    switch (SelectedItem.Tag.ToString())    {        case "Solution":            SolutionTree.ContextMenu = SolutionTree.Resources["SolutionContext"] as System.Windows.Controls.ContextMenu;            break;        case "Folder":            SolutionTree.ContextMenu = SolutionTree.Resources["FolderContext"] as System.Windows.Controls.ContextMenu;            break;    }}

You could define the ContextMenus in several styles and select the style using a ItemContainerStyleSelector, based on those attributes.

Or you could directly specify an ItemContainerStyle and select the appropriate ContextMenu using triggers

<TreeView>  <TreeView.Resources>    <ContextMenu x:Key="ScaleCollectionPopup">      <MenuItem Header="New Scale..."/>    </ContextMenu>    <ContextMenu x:Key="ScaleItemPopup">      <MenuItem Header="Remove Scale"/>    </ContextMenu>  </TreeView.Resources>  <TreeViewItem Header="Scales" ItemsSource="{Binding Scales}" ContextMenu="{StaticResource ScaleCollectionPopup}">    <TreeViewItem.ItemContainerStyle>      <Style TargetType="{x:Type TreeViewItem}">        <Setter Property="ContextMenu" Value="{StaticResource ScaleItemPopup}"/>      </Style>    </TreeViewItem.ItemContainerStyle>  </TreeViewItem></TreeView>
