Gets or sets the physical path of the requesting page, even in design mode.
At run-time, this property simply returns the value of the Page.Request.PhysicalPath property. At design-time, this property is set by the PagePorter framework to be the path to the current file in the IDE. If you are using this object outside the PagePorter framework in design-mode, you will have to set this property manually, or some of the features of the control may not display correctly.
