Since when is a Refresh a PostBack?

[Jonathan Wood]

I'm getting into the habit of checking IsPostBack in my Form_Load handler
and not updating the page if it is a postback.

However, I notice that if I hit my browser's refresh button, the page
refreshes without any data.

Since when is a refresh a postback?

Thanks.

The Refresh button reloads the page in exactly the way that it was
originally loaded... If it was originally loaded as a result of a postback,
then hitting the Refresh button will cause it to be reloaded as from a
postback...

This is standard browser behaviour...

A postback is no more than setting 2 hidden fields __EVENTTARGET and
__EVENTARGUMENT and calling the form's submit() method.

What hitting the Refresh button does is repeating the last submit() call
with exactly the same settings of all fields. Hence you get the effect you
are observing.

Yeah, okay, I may have more going on here than I originally thought.

Thanks for putting me back on the right track.

You still persist in top-posting, though...

Learning how to snip would be useful too...
