  Hi,
  
  I have a RadTrackBarElement hosted in a CommandBarHostItem. It displays correctly, and I have configured certain properties such as removing the tickmarks etc. However, I just cannot get the BackColor of the trackbar to take on the colour of the parent item i.e. the CommandBarStrip it is hosted in. The CommandBarHostItem.BackColor is at it's default which appears to be Color.Transparent.
  
  How do I set the BackColor of the TrackBar so that it actually changes? If I look through VSB, it appears that RadTrackBarElement.BackColor is all that's required, but this doesn't work.
  
  Cheers,
  
  Steven

  Hello Steven,

  Thank you for writing.
  
  The issue with the RadTrackBar back color is a known issue, which we will address in one of our future releases. Until then you can set the back color of the RadTrackBar through the following code:

  TrackBarPrimitive primitive = this.radTrackBar1.TrackBarElement.Children[0] as TrackBarPrimitive;

  primitive.BackColor = Color.Transparent;

  
  I hope this will help you. If you need further assistance, I would be glad to provide it. Kind regards,
  Ivan Petrov

  Hi, that's perfect thanks, it works as expected.
  
  Note that I am using the RadTrackBarElement directly, so the .TrackBarElement in the above code can be removed.
  
  Cheers,
