  I have put code into my application to remove an item from the carousel.  It removes it, but the item stays in view at the selected item position.  As I scroll around, the item is still there in the background.
  
  

  rCarFolders.Items.Remove(rCarFolders.SelectedItem)

  rCarFolders.Refresh()
  
  Help!

  Hi Seth,
  
  Thank you for contacting us.
  
  I reproduced this issue. The following workaround removes the selected item correctly:
  
              if (this.radCarousel1.SelectedItem != null)
              {
                  RadItemCollection col = new RadItemCollection( this.radCarousel1.Items );
                  col.Remove((RadItem)this.radCarousel1.SelectedItem);
                  this.radCarousel1.Items.Clear();
                  this.radCarousel1.CarouselElement.BeginUpdate();
                  this.radCarousel1.Items.AddRange(col);
                  this.radCarousel1.CarouselElement.EndUpdate();
               }
  
  Could you please check in your code that rCarFolders.SelectedItem is different from null?
  
  I believe this will help you. You can write me back if I could be of further help.

  Thanks for the workaround, it would be good to have this fixed at some point. I trust you have it logged as a defect? :)

  Hello Dylan,
  
  Thank you for contacting us.  We added the issue to our ToDo list. Extending the current behavior is not a simple task and hence I cannot give you a specific time frame about implementing it, however, the more people request that feature the higher its priority will be.
  
  Please excuse us for the introduced inconvenience.
  
  Kind regards,
  Peter

  Hello Peter,
  
  I have the same problem. The workaround works fine, it actually removes the item correctly. But since the .clear and .addrange methods are used, all remaining items  in the collection "fly" again  to an initial position in the carousel. Is is possible to avoid this effect and just remove the item without notice for the user?
  
  Thanks,
  Rafael Poggi

  Hello Rafael Poggi,

  RadCarousel cannot remove an item without recalculation of the coordinates of the other items. e.g. animation cannot be avoided. To avoid visual glitches we do not allow removing single items. You should call

  radCarousel1.Items.Clear();


   
  and add all other items after that
   
  

  radCarousel1.Items.AddRange(myItems);

  Please, excuse us for the inconvenience.

  Kind regards,
  Peter
