Gets or sets a value indicating whether postback event data should be validated. This API is obsolete. For information about how to develop ASP.NET mobile applications, see the www.asp.net/mobile Web site.
Assembly: System.Web.Mobile (in System.Web.Mobile.dll)
ASP.NET controls create client-side scripts to raise postback events on the server. It is possible for a malicious user to use the postback script to send arbitrary post events to server controls.

Event validation is not supported in mobile pages.
