You don't have to define a Canvas and build your own lines. You can instead edit the default ControlTemplate
of the RadTreeView
control and modify it to better suit your needs. For example you can remove the horizontal lines and only leave the vertical line before the RadTreeViewItems
. Then you can also move this line at the top of the RadTreeViewItem ControlTemlate
. I attached a sample demonstrating such an approach. Please give the project a try and let me know if it represents a style close to what you had in mind.
If you need to further customize the template, you can send us a snapshot illustrating your requirements and we can assist you in implementing them.
