  I want to launch a new form after a carousel selected element has rotated into position 
  but I can not find any (end of rotation event) that will allow me to do this.
  Is there one or is there a techinque I can use to simulate this

  Hello Chris,

  Thank you for writing.
  
  I would suggest that you handle the SelectedIndexChanged event. This event will be fired when the carousel items are rotated.
  
  I hope this helps. If you have any other questions or comments, please let me know.

  All the best,

  Thanks for your suggestion ,but it doesn't help
  That event fires prior to rotation not after rotation has completed.

  Hello Chris,
  
  Sadly, currently there is no such thing, but there are 2 ways you can achieve this, either create a custom event on the form that will fire when the animation has completed, either create a custom Carrousel,
  I will post here examples of how to achieve both of these things:
  

  // create a new Event here

  public event EventHandler EventThatFiresAfterRotationCompleted;

   

  public Form1()

  {

      InitializeComponent();

     // handle the selected index changed operation here, and create a timer that will fire after the animation for the carousel is finalized

      radCarousel1.SelectedIndexChanged += delegate

      {

          var timer = new System.Windows.Forms.Timer();

          timer.Interval = radCarousel1.AnimationDelay * radCarousel1.AnimationFrames;

          timer.Tick += delegate

          {

              timer.Stop();

              if (EventThatFiresAfterRotationCompleted != null)

              {

                  EventThatFiresAfterRotationCompleted(radCarousel1, EventArgs.Empty);

              }

          };

          timer.Start();

      };

       

      //register for event

      this.EventThatFiresAfterRotationCompleted += new EventHandler(Form1_EventThatFiresAfterRotationCompleted);

  }

   

  void Form1_EventThatFiresAfterRotationCompleted(object sender, EventArgs e)

  {

      MessageBox.Show("AnimationCompleted");

  }

  
  Or the second one with the custom Carrousel:
  

  public class CustomRadCarousel : RadCarousel

  {

      public event EventHandler EventThatFiresAfterRotationCompleted;

   

      public CustomRadCarousel()

          : base()

      {

          SelectedIndexChanged += delegate

          {

              var timer = new System.Windows.Forms.Timer();

              timer.Interval = this.AnimationDelay * this.AnimationFrames;

              timer.Tick += delegate

              {

                  timer.Stop();

                  RaiseEventThatFiresAfterRotationCompleted();

              };

              timer.Start();

          };

      }

   

      private void RaiseEventThatFiresAfterRotationCompleted()

      {

          if (EventThatFiresAfterRotationCompleted != null)

          {

              EventThatFiresAfterRotationCompleted(this, EventArgs.Empty);

          }

      }

  }

  
  Hope this helps, if you have any other questions or comments, please let me know,
  
  Best Regards,

  Hello Chris Lynch,

  Thank you for the provided details.
  
  I could suggest that you use RadCarousel.CarouselElement's AnimationFinished event.
  This event will be fired when the animation is finished.
  
  Let me know if you have any other questions.

  Sincerely yours,
  Peter
