There are two approaches that I can suggest for your scenario:
- Change the BackColors of normal RadButtons. However, this approach requires keeping track of the button state by holding a boolean variable.
- Using RadToggleButtons. They automatically toggle on/off when you click on them and you do not need to keep the boolean variable.
You can also combine these two approaches - use RadToggleButtons for automatic on/off states and setting their BackColors according to your preference. I have attached a sample project to demonstrate the usage of RadButtons and RadToggleButtons.
If you have additional questions, feel free to contact me.
