I have a page p1.aspx which has an iframe, if1, and a button sb1. The source of if1 is p2.aspx which has a web user control uc.ascx. In uc.ascx, there is a textbox, tb1, for user to enter a string.
My question is:
Is it possible to get the text of tb1 of uc.ascx in the p1.aspx when I click the button sb1? And How?
Thanks in advance.
