Answer 1

你可以点击事件处理程序

来做到这一点

  <TreeView Tag="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type ComboBox}}"  MouseClick="treeview_MouseClick" ItemsSource="{Binding Children}" x:Name="Tree">

使用Click事件可以获得ComboBox

private void treeview_MouseClick(object sender, RoutedEventArgs e)
{
    try
    {
        TreeView treeview = sender as TreeView;
        if(treeview == null)
            return;
        var combobox = treeview .Tag as ComboBox;
        combobox .SelectedItem = treeview .SelectedItem;
    }
    catch (Exception e)
    {

    }
}
