Refresh Parent window from child window causes problems

Raj
Hi All,
I have a problem with trying to refresh the parent window from
child window in order to update data in the parent window.

The sequence of events are
1) I click a button in the parent window to open a child window thru
javascript
window.open

2) I have some functionality in the child window that changes the data
in the parent window.

3) I need to refresh the parent window on child window closing

I read some posts here and I did window.opener.l ocation.reload( true)
and window.opener.r eload(true). when I did this, IE came up saying
"This page cannot be refreshed without resending information, Click
retry to send the information again ...." and all that crap when I hit
this the page is refreshed, but the ItemCommand of the parent window
had the same event that opened the child window and it opened it
again.

So even when I close it, I end up with the same window again.

Can someone please help me to refresh my parent window without this
message box and I dont want to have the child window open again

TIA

Hmmm, to me it seems quite obvious that the Refresh function re-opens your child window. This was exactly what happened when you loaded your page the last time - and Refresh just repeats this loading process.

I'd set the parent window to a new location in order to have it "forget" its current state. Either by setting it to "opener.locatio n=opener.locati on;" or if this doesn't work "opener.locatio n=null; opener.location =opener.locatio n;" or something.

The problem lies in the way that WebForms work (POSTing back to themselves),
and the way the browser works. When a browser tries to refresh a page that
is the result of a form submission, it is necessary to re-submit the form,
as the form was generated as a result of a previous POST request.

Your only solution is to not refresh the browser in the parent window, but
to send a fresh GET request for the page, as if hyperlinked (as in
"parent.locatio n = 'someURL'"). This may be problematic, as you probably
want to retain the state of the page as it presently exists, and a fresh
request for the page will return it in its' initial state. A workaround for
this would be to append a QueryString to the request, so that the
server-side class can read the QueryString in order to update itself to the
proper state. Another workaround would be to re-post the parent form (as in
"parent.for ms[0].submit()"). Again, you would have to make sure that the
parent page could restore itself to its' correct state based upon the
results of the post.

Overview: I have a custom web app that has an 'Inbox' that refreshes every 30 seconds. One user uses Outlook to host the web page. Using IE, the refresh works fine. If the user is working in another window, the web page quietly refreshes in the background. Hosted in Outlook, the refresh causes Outlook to come to the front on every refresh. Or in XP, causes the toolbar icon to flash.

Hi, I've got a Web page which can become a parent window : some links use "window.open" to open the desired link into a new child window. This parent window has got an auto-refresh functionality (<meta http-equiv="refresh" content="60">). My point is that when I'm looking at the child window, I don't want the parent window to take the focus when refreshing. Does anybody have an idea ? Thanks !
