Sys.WebForms.PageRequestManager abortPostBack Method

Stops all updates that would occur as a result of an asynchronous postback.




The abortPostBack method stops the currently executing postback. To cancel a new postback, provide an event handler for the initializeRequest event and use the cancel event of the Sys.CancelEventArgs class.
