Mike,

>I was troubleshooting some problems in a web page, where I was storing state info into session variables within the page’s PreRender event when I realized that the PreRender event wasn’t firing in the page’s lifecycle.

You definitely found something here...the mmBaseWebPage.OnPreRender() method is only calling base.OnPreRender() if a "FocusedControl" is specified for the page. We'll fix this problem, but for now you can specify a FocusedControl for your web pages and the PreRender event should fire.

Regards,
