The C1Reflector control will, by default, automatically update the reflection each time the control's content is updated. This is useful when you're using controls with interactive parts, such as the C1Reflector control or the C1Accordion control. The automatic update ensures that every movement of these controls will be shown in the reflection, so that if a user expands an accordion pane, for example, the accordion pane in the reflection will also be expanded. 

If you'd prefer not to have your content automatically updated, you can turn the C1Reflector.AutoUpdate property to False.
