refresh button help

[=?Utf-8?B?cm9kY2hhcg==?=]

hi all,
i betcha here's a question never asked before ;)
i have a simple web form with a gridview and a button. the button doesn't do
anything but a postback.
i load up the gridview from the database, hit the button, then hit the
refresh button and here's where my question occurs. I get a message saying
that "it needs to resubmit/resend the data?"

what is happening here and how do I resolve this undesired message?

thanks,
rodchar

RE: refresh button help

this is a standard browser question. it happens whenever a refresh is
actually a postback of form data. this hack was added to most browsers due to
the adbundance of poorly written web applications that could not handle this
event (double billing credit cards, etc).

you can use ajax instead, or do a redirect after postback to avoid this
message.

Re: refresh button help

Rodchar:
When you hit the "refresh" button, the browser need to resend the form's
fields to recreate the page, this is the reason to show the dialog with
message "it needs to resubmit/resend the data?".
To prevent this you can add a button to the webform that recreate the
page and use this instead the browserr's "refresh" button.
