References the hosting IPage.
public IPage Page {get;}
This object reference is available to page element property script bindings and event handlers, and to page-level scripts.
For application-level scripts (i.e., defined inside .ss files on the server), this reference returns null.
This example shows how to retrieve the PageDescription property of the
IPage object.
var s = string.Format("Page description: {0}", Page.PageDescription);
WV.MsgBox(s);
