I hope this information helps. Should you have further questions I would be glad to help.
In the previously provided solution, it is shown how to make RadTreeView control looks transparent so the background image can be see through it. Following the brief information that you provided, it is not very clear what exactly you would like to achieve but I suppose that you want some opacity of the color in treeview. If you do so I can suggest using the Color.FromArgb method where you can specify the alpha component of the Color.
You can refer to the following thread from StackOverFlow as well where a similar questions was already discussed: https://stackoverflow.com/questions/5064774/opacity-on-control
However, if you need any further assistance I would kindly ask you to give more details about what is the final goal that you would like to achieve. It would be of great help if you can provide a picture or video of the desired look.
I hope this information helps. Let me know if I can assist you further.
