I am glad to hear that you have solved this issue. Regarding your questions:
It depends on the theme. You can customize almost every aspect of RadTreeView
and all our controls by using the Visual Style Builder
tool. Actually, the control has a blue border in its default theme. Could you please specify where you want to add a border?
We hide the text for a better readability. The node layout is fully customizable and you can add your own elements where you can show custom texts.
I hope this helps. If you have any further questions, do not hesitate to ask.
