Remarks

The ActionUrl property of the PostBackOptions class specifies the URL for the action attribute of a Web Forms page. The ActionUrl property can be used to specify which Web Forms page to post data back to, causing a cross-page post. For more information on cross-page posting, see Cross-Page Posting in ASP.NET Web Forms.
