If it does the job in your particular scenario, I see no problem in using those properties. However, I still don't see an issue with the definition of the control you have us. I ran the code at my end and in my oppinion, RadSlider behaves properly. Please take a look at the recorded video
and attached sample project. Let me know if I am missing anything. I'd be glad to further assist you.
All the best,
the Telerik team
