    Is there a way to allow the user to click on the 1st item in the treeview, and then shift+click on a later item and have it select all items in between?

    You need to handle ItemExpanded event to select 1st item on expanding a Parent node as:

            private void Item_Expanded(object sender, SourcedEventArgs e)
                var node = e.Source as C1TreeViewItem;
                if(node != null)
                        node.FirstNode.IsSelected = true;

    In order to achieve the requirement to select items using Shift+Click. You need to set SelectionMode=True. On expanding parent node the first item will be selected and then shift+click on a later item will select all items between them.

    Please refer the attached sample for the same :
