hello, i have a problem in refreshing a page. the problem happens when i
click a button that does a certain action in a web page, such as inserting a
record into the database, if now i refresh the page (press f5), the action
repeats itself and another identical record is inserted too.
i discovered that the button_click event is called when i refresh the page.
so the problem is that when i refresh the page, the last action that i have
done on the page is refired.
if anybody can tell me how to solve this problem ill be thankfull...

You can't exactly solve it. What you can do is to handle it on the server.
For example, you could set a Session variable when the insert occurs, and
check it before doing the insert. If the Session variable is there, you know
the record has been inserted already. Of course, you have to remove the
Session variable at some point in order to do another insert. But of course,
there are ways of doing that as well. There are other solutions as well. How
you handle it is up to you, based upon the functionality of your page, and
your creativity.

The problem is that when you press F5 IE sends excatly same info to the
server.
And server can not distinguish between first request and second.
The easiest thing is to redirect to the page (it could be the same page).

Hi,
I have a private website for 20 people that is similar to a web email client
like hotmail.
There are two frames, one on the left with links for "New", "History",
"Todays" and a frame on the right with a table for viewing the contents of
these messages. The left pane checks back with the server every few seconds
to see if any new messages need to be processed and updates count
accordingly.

Hey guys, please HELP
I am going nuts with the datagrid control.
I cannot get the damn control to refresh. I am using soap to get information
from a web service. I have an XML writer output the file to a folder, and
then I read it back into the dataset using the dataset1.readxml. Up to this
point, everything works wonderfully. The query executes, the dataset gets
populated, and I get the results displayed in the datagrid.
