Thank you for this question.
The behavior experienced is not an issue, but this is the normal behavior. The image that you set is covered by the FillPrimitive which draws a fill gradient. In order to see the image, you should hide the FillPrimitive. There are two approaches to do this:
|((FillPrimitive)this.radCarousel1.CarouselElement.Children).ShouldPaint = false;
|((FillPrimitive)this.radCarousel1.CarouselElement.Children).Visibility = Telerik.WinControls.ElementVisibility.Hidden;
This is now scheduled for documentation in one of our next versions. If you have additional questions, feel free to contact me.
