Syntax
'Declaration
 
Public Shadows ReadOnly Property UIElement As UltraWeekViewUIElement
public new UltraWeekViewUIElement UIElement {get;}

The control's UIElement property exposes a ChildElements collection under which all of the control's many individual UIElements appear as descendants.

Example
Demonstrates how to optimize the control's display so that only the day with the most appointments is visible
