Pass events or data to IFRAME

[Peter]

I have a webform on this form is a User Control and another webform in
IFRAME
On the User Control there is a save button.

I want to click this button and somehow tell the webpage in IFRAME that the
button was clicked, how would I do that?
(in other words I want to save the webform data in IFRAME when the save
button is clicked)

If you want to "talk" to an iframe using client side script, you just need
to use something like this:

document.frames ("frameName").d ocument.forms(" formName").subm it().

Thanks for your help!

What about if there are more than one button, say 'Save' and 'Delete'
buttons how do I know which one was clicked?

Hi Peter,
Thanks for posting in the community!
From your description, you'd like to post back a sub page in a iframe when
a certain button on its parent(containe r page) is clicked. Also, you'd like to pass the certain button's id to the sub page so that in the sub page's
postback process ,you can got the info on which button in container page is clicked, yes?
If there is anything I misunderstood, please feel free to let me know.

As for this problem, Chris has supply the correct direction that use the
javascript to submit the page in the iframe. And as to how to pass the
button's id info, my suggestion is putting a hidden field(<input
type=hidden value=" .." ... > to store the info, and when a certain
button in container page is clicked, first set the hidden field in subpage
and then submit it. For detailed illustration, I've attached a couple of
sample pages using this means.

In addition, I've some further suggestions on this issue:
1. When you used <Iframe> to contain a certain page, then if the container
page is posted back, it'll refresh the sub page also. So as for your
situation, if you want to notify the sub page for the parent page's event
and then do some operations, you need to use different means according to
the button's event type(server button event or client event)
(1): If is the server button event, you'd like to notify the sub page after the sub page is posted back , thus, the sub page can do the certain
operations after it is refreshed caused by its parent page's postback.

(2): If you notify the sub page at the buttons' client click event, since
the parent page isn't posted back, you needn't to code as (1), just call
javascript to posted back the sub page.

I've including the both situations in my sample page, you may refer to it
if you feel anything unclear.

2. I've noticed that you used UserControl to contain some certain buttons
and which will need to control some other element ourside it(in its
container page). I think sometimes, it's better to avoid using UserControl
since UserControl will make its controls's clientID changed( not the same
as those which are directly put onto a page), that'll cause some problems
or difficulties when we implement javascript code on them to associate with some other pages or elements.
Do you think so?

Please check out the preceding suggestions and my sample pages. If you have anything unclear, please feel free to post here.
