Refresh Parent window from child window causes problems

P: n/a
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.location.reload(true)
and window.opener.reload(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
Raj

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.location=opener.location;" or if this doesn't work "opener.location=null; opener.location=opener.location;" 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.location = '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.forms[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.
