  Hi,
  
  I am just getting to terms with the carousal and its working great. There is just a couple of things I am trying to get right. Maybe you can help me.
  
  I have created some test code which adds the image list at runtime just looking at a directory. Code is displayed below. The code works fine but all the items are the same size. What I need is the selected item to be a larger size so they stand out from the rest. Also if its not too much work I want the rest of the items in the background to be slightly dimmed out just to emphasize on this.
  
  PLEASE HELP...
  
  Thanks
  
  
  
  private void CreateCarouselItems()
          {
  
  
              //pictureBox2.Image = Image.FromFile("D:\\IMAGES\\1.jpg");
  
              int[] myInterger = new int[1];
              for (int i = 1; i < 100; i++)
              {
                  RadButtonElement carouselItem = new RadButtonElement();
                  carouselItem.ImageAlignment = ContentAlignment.MiddleCenter;
                  carouselItem.TextAlignment = ContentAlignment.MiddleCenter;
                  carouselItem.TextImageRelation = TextImageRelation.ImageAboveText;
                  carouselItem.ShowBorder = true;
                  carouselItem.Text = "Peter Pan";
                  carouselItem.ForeColor = Color.WhiteSmoke;
                  carouselItem.TextRenderingHint = System.Drawing.Text.TextRenderingHint.ClearTypeGridFit;
  
                  carouselItem.BackColor = Color.YellowGreen;
  
  
                  Bitmap b;
                  b = (Bitmap)Image.FromFile("D:\\IMAGES\\" + i.ToString() + ".jpg");
                  carouselItem.Image = ResizeBitmap(b, 90, 60);
  
  
                  this.radCarousel1.Items.Add(carouselItem);
              }
  
  
          }

  Ok,
  
  I have had some luck in the selected index change even. But the only problem is that when the item I made larger moves along it remembers its image size so I guess I also need to reset all the other items as well as the selected item. I still have no idea how to dim out the unselected items. This is the code I have got so far...
  
  private void radCarousel1_SelectedIndexChanged(object sender, EventArgs e)
          {
              RadButtonElement carouselItem = (RadButtonElement)radCarousel1.SelectedItem;
              Bitmap b;
              b = (Bitmap)Image.FromFile("D:\\IMAGES\\" + "2" + ".jpg");
              carouselItem.Image = ResizeBitmap(b, 150, 100);
  
          }

  Hi david,
  
  Thanks for writing.
  
  I have prepared a small example on how you can dim and resize background pictures.
  
  Hope this helps.
