Please use 

 e.Handled=true;

in your treeViewItem.Expanded event handler. That way it will only fire for the actual item expanded and not bubble route to the parent tree view items.

You'll need to respond to the AfterExpand event.

By restricting to the click you are shutting out keyboard users.

EDIT

Sorry, that's WinForms. Here is the WPF solution:

<TreeView TreeViewItem.Expanded="TreeViewItem_Expanded" />
