Thank you for writing.
You can easily achieve this with the RadScrollablePanel and two RadRepeatButtons. I have attached a sample project where I have implemented this scenario. You have to set the RadScrollablePanel AutoScroll property to true and set its Size to (0,0). You can then use the PerformLargeIncrement, PerformLargeDecrement or PerformSmallIncrement, PerformSmallDecrement to scroll the content of the panel when the corresponding button is clicked.
If you have further questions, feel free to ask.
