No Page_Load event when aspx is in iFrame?
It might be me but...
I dont seem to get a Page_Load event when a opening an ASPX in an iFrame. I
do geta Page_Load event when an item on the ASPX (inside the iFrame) is
clicked but then IsPostBack=False by now!. The ASPX is opened via client
side script (into an iFrame) inside a .HTM file (as ASPX postback causes
problems in a modal internet explorer dialog if not in an iFrame!)
Anyone know how to get around this - i need to examine querystring variables
on 1st load!
Current setup...
MAIN.aspx - contains a link (to popup.htm), it contains client script...
window.showModalDialog('popup.htm','popup.aspx?v1= " &
txtStartDate.Text &
"','status:no;dialogWidth:250px;dialogHeight:250px ;dialogHide:true;help:no;s
croll:no')
in 'popup.htm' - client script sets the src to the 2nd arg
('popup.aspx?v1='???') supplied in showModalDialog
<script language='javascript'>
//<!--
function load()
{
var src = window.dialogArguments;
if (src) {
document.all.Frame1.src = src;
}
}
//-->
</script>

Marina #2 Re: No Page_Load event when aspx is in iFrame?
I used iframes extensively in a particular project, and the page_load event
fired just fine. And here also, the src of the iframe was assigned at
runtime, not hard coded. Whether or not a page is loaded into an iframe
should not matter.
I think your problem lies elsewhere.
Try using a very simple page, that just does a response.write in the
page_load. Try posting your code here...

Stevie_mac #3 Re: No Page_Load event when aspx is in iFrame?
Thanks for your response, I did that & response.wrote now.ToString(). What
i've found is that the time was written the 1st time the aspx was shown but
always showed the same time in each following load (Probably something to do
with caching i guess?) Note: the aspx page is loaded by assignment (client
side) to the src property at run time - but within a .htm file - inside a
Modal dialog! Not sure how the page_load isnt called 2nd, 3rd time.
CODE...
*** Main.aspx (inside Page_Load)***
Button1.Attributes.Add("onclick", "var
strReturn=window.showModalDialog('popup.htm','popu p.aspx?v1=" &
txtStartDate.Text & "','status:no;

(strReturn) document.forms[0].txtStartDate.value=strReturn;")
Button2.Attributes.Add("onclick", "var
strReturn=window.showModalDialog('popup.htm','popu p.aspx?v1=" &
txtEndDate.Text & "','status:no;
dialogWidth:250px;dialogHeight:250px;dialogHide:tr ue;help:no;scroll:no'); if
(strReturn) document.forms[0].txtEndDate.value=strReturn;")
