    I'm using the RadPanel Bar (Demo) with 7 Group elements, each with EnableHostControlMode checked and each Panel filled with 3 to 9 Checkboxes or Radiobuttons.
    All Groups as expanded.
    The Scrollbar appears. Appart from that scrolling is extremely slow, when using the "arrow-buttons", I experience another problem:
    I click on the slider, slide it (up and down) and release the mouse button, before all the repainting is done.
    Now many optionbuttons or checkboxes stay just where they are, overlapping the groupbars or each other.
    Can I speed up the performance of repainting the Controls?
    Can you fix the bug or tell me a workaround?

    Hello Stefan,

    Could you please open a new support ticket and send us a sample application demonstrating the behavior you describe? I will review it to see what could be improved in your case. The behavior using the arrow button is expected as the SmallIncrement value of the scroll bar is set to 1 by default, so you would scroll up/down only by one pixel per click.  

    I'm looking forward to your reply.

    All the best,
    the Telerik team
