Hello Nebras ,
Thank you for writing.
I confirm that this is a limitation in the current implementation of RadTrackBar
. We plan to refactor and improve this control, however the only solution available at this time is customizing its properties with code as you suggested in your post.
Should you have further questions feel free to ask.

Q1’11 SP1 of RadControls for WinForms is available for download
; also available is the Q2'11 Roadmap
for Telerik Windows Forms controls.
