jqModal iframe issue

I have a asp.net page (page1.aspx), inside that I have a iframe, Inside the iframe I am loading another page(page2.aspx). Inside开发者_开发知识库 that page(page2.aspx) I have a button. When I click on that button jqModal pops up. It comes up covering the iframe which is in page2.aspx. How can i make the jqModal div to allocate parent page(page1.aspx) full space.

Presumably you have to pass through the identifier for the parent page all the way through to the jqModal div and use that as the anchor point.
