I need help to reload an iframe from within 2 iframes, already tried parent.document, response.redirect, but what I request does not occur.
If I use response.redirect (url), iframe1 is reloaded inside Iframe 3.
If I try to use parent.document.getelementbyid ('iframe1') or parent.document.getelementbyid ('iframe3') or parent.document.getelementbyid ('<% = iframe1.ClientID.ClientID% >') or parent.document.getelementbyid (''), is returned null.
I've attached an image of what I'm trying to do.
I want it when I click the button inside of iframe3, that iframe1 is reloaded.
