Updating an UpdatePanel from another webpage.

I have an UpdatePanel on a page. This webpage opens up a new web page. Is it possible to force an update of the UpdatePanel on the first webpage from the second page?

hello.

yep, that should be possible. if your main problem is establishing the comunication from the child to the parent window, then take a look here:

But what can I call on the parent page to force a submit of the panel. Would I, for example, have to call the submit event of a button which in turn will submit the updatepanel or is there an event which I can call directly on the updatepanel itself? I don't really want to have to add an extra control to raise the submit event which would be visible to the user.

hello.

yes, that is the idea... you can add a button to the page and hide it (say, set it's css display to none). so, your parent page can expose a method that is responsible for calling the click methdo over that button (this method will be called from your child page).
