Gets or sets the URL of the requesting page, even in design mode.
At run-time, this property simply returns the value of the Page.Request.Path property. At design-time, this property is set by the PagePorter framework to be the URL 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.
