ASP.net referesh problem

[Rahul]

We have an ASP.net 2.0 application. The page has a linkbutton that presses
and we make visible a panel that has an update button. He presses the
updated button and the database gets updated. We make the panel invisible
again. But if the user presses the refresh button, the same event handler
gets triggered again and ends up updating the database. This messes up the
data.

Is there a way to avoid this. I know that I can do response.Redirect and
that solves the issue but now the page had to do 2 calls to the server.
There has to be a more elegant way of solve this problem.

Thanks
Rahul

You may want to try http://aspalliance.com/687 or

Note though that this is AFAIK the correct behavior (my understanding is
that "refresh" is intended to just repeat the last request whatever it is).

There are a number of solutions to this, one of the simplest to implement
(for starters, just to "Get to First Base") is to set a boolean Session
variable that indicates the button was pressed. Just check this value on a
refresh and if it is true, return without any action.
