We have a few ASP.net apps where we needed confirmation dialogs with buttons
in datagrids. The code goes something like this (in the ItemDataBound event
for the grid):

strJavaScript = "javascript: return confirm('Any changes made to this
scenario cannot be reversed. Also, results to a changed scenario cannot be
viewed until the scenario is submitted again. Continue with edit of scenario
?');"
btnLink = CType(e.Item.FindControl("cmdSelect"), LinkButton)

btnLink.Attributes.Add("onClick", strJavaScript)

This has worked flawlessly until recently. Now, on my development machine,
the dialog will still appear, but no matter which button I click it goes
ahead as if I clicked "OK". The other developers do not have this issue, it
still works for them. This happens with apps that have been in production
for a while. A few weeks ago it worked fine from my machine, now it doesn't.

My guess is that it is my browser. It's IE 6.0.2800.1106 SP1. Several of the
"Q" updates have been pushed onto machine, but nothing that the other
machines don't have. Security settings in IE look kosher. It seems as if the
javascript is running because I see the dialog. It seems that the "return"
value is being ignored.

Anyone ever experience something like this? I've googled, but no luck. Maybe
not wording it correctly.

Thanks for any insight you can provide.

Hi

Loose the javascript: bit
btn.Attributes.Add("onclick","return confirm('blah')");

Thanks for the response, but it made no difference. Still behaves the same
way.

When I view the source I can see the code in there for the onclick, so
that's being recognized.

its a known IE bug. it fails cancel the postback based on the return value.
while there is no fix, there is a workaround.

allowPostbackScript = @"<script>
function allowPostback(v) {
if (!v && document.all) event.returnValue = false;
return v;
}
</script>
";

RegisterStartupScript("allowPostback",allowPostbackScript );

strJavaScript = "javascript: return allowPostback(confirm('Any changes made
to this
scenario cannot be reversed. Also, results to a changed scenario cannot be
viewed until the scenario is submitted again. Continue with edit of
scenario
?'));"
