    CreateKeyframe Method (RangeTrack)
    In This Topic
    Create a new keyframe.
    Syntax
    Public Function CreateKeyframe( _
       ByVal range As Range, _
       ByVal atTime As TimeSpan, _
       ByVal transition As AnimationTransition _
    ) As Keyframe

    Parameters

    range
    The value of the range.
    atTime
    The time at which to insert the keyframe in the track.
    transition
    The transition for min and max value of the range. In the UI the default is ArcGIS.Core.CIM.AnimationTransition.Linear.
    Remarks
    If a keyframe already exists at that time it will be overwritten. The time is rounded to the nearest millisecond. When you create a keyframe the specified transition will be used for the min and max values of the range. It is possible to change the transitions for the min or max by settting the transition on the keyframe./>
    Example
    Create Range Keyframe
    public void CreateRangeKeyframe(ArcGIS.Desktop.Mapping.Range range, TimeSpan atTime)
    {
      var mapView = MapView.Active;
      if (mapView != null)
        return;
    
      var animation = mapView.Map.Animation;
      var rangeTrack = animation.Tracks.OfType<RangeTrack>().First(); //There will always be only 1 RangeTrack in the animation.
      rangeTrack.CreateKeyframe(range, atTime, ArcGIS.Core.CIM.AnimationTransition.Linear);
    }
