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.

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.

VB.NET
C#

'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");
}
