The RenderPostBackEvent method writes a postback event as a scriptless hyperlink, including the possibly chunked UrlEncode view state, __EVENTTARGET=target, __EVENTARGUMENT=argument, __PREVIOUSPAGE=currentFilePath parameters, and an accessKey="accessKey" attribute.
View state is encrypted if the enableViewStateMac attribute of the pages Element (ASP.NET Settings Schema) configuration element is set to true.
Notes to Inheritors:
When you inherit from the PageAdapter class, you can override the RenderPostBackEvent method if a different format is required for the postback event hyperlink or the browser has other unique requirements. For example, some browsers require the hyperlink text to be nonempty if the link is to render. You can also override RenderPostBackEvent if limited resources prevent including the view state as a URL parameter. The RenderPostBackEvent base method does not write an attribute for softkeyLabel.
