    'Declaration
     
    
    Public Event AnnotationRotated As GdViewer.AnnotationRotatedEventHandler
    public event GdViewer.AnnotationRotatedEventHandler AnnotationRotated
    public event AnnotationRotated: GdViewer.AnnotationRotatedEventHandler; 
    In JScript, you can handle the events defined by another class, but you cannot define your own.

    public:
    event GdViewer.AnnotationRotatedEventHandler^ AnnotationRotated
    Remarks
    Be aware, that this event only handles GdPicture/XMP annotations.
    Example
    How to add this event to your GdViewer control. This example shows you how to address the currently rotated annotation to find out the rotation angle.
    'We assume that the GdViewer1 control has been properly integrated.
    Friend WithEvents GdViewer1 As GdPicture14.GdViewer
                
    'Add the event.
    AddHandler GdViewer1.AnnotationRotated, AddressOf GdViewer1_AnnotationRotated
                
    'Define the event.
    Sub GdViewer1_AnnotationRotated(ByVal AnnotationIdx As Integer) Handles GdViewer1.AnnotationRotated
        Dim annot As GdPicture14.Annotations.Annotation = GdViewer1.GetAnnotationFromIdx(AnnotationIdx)
        MessageBox.Show("The annotation with the index " + AnnotationIdx.ToString() + " has been rotated by " + annot.Rotation + " degrees.", "GdViewer.AnnotationRotated")
    End Sub
    //We assume that the GdViewer1 control has been properly integrated.
                
    //Add the event.
    GdViewer1.AnnotationRotated += GdViewer1_AnnotationRotated;
                
    //Define the event.
    void GdViewer1_AnnotationRotated(int AnnotationIdx)
    {
        GdPicture14.Annotations.Annotation annot = GdViewer1.GetAnnotationFromIdx(AnnotationIdx);
        MessageBox.Show("The annotation with the index " + AnnotationIdx.ToString() + " has been rotated by " + annot.Rotation + " degrees.", "GdViewer.AnnotationRotated");
    }
