My most sincere gratitude to anyone who can help me work
around this!
I have work that needs to be done in javascript on the
client whenever a page is unloaded.
To this end, I subscribe to the unload event (client side
not server side) of the <body> HTML element through
javascript.
However, if I turn on smart navigation, any button that
does a server.transfer fails to fire the client side
unload event.
I have included two example pages that duplicate the
behavior. To run the example, create two pages called
webform1.aspx and webform2.aspx and copy the html and code
from this message.
Any explanation or work around is greatly appreciated!
Thanks for your time.
