iframe 100% height not applying
===

I have a site with master pages and the only thing I want on one page is this:

    <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" Runat="Server" style="margin:0px;padding:0px;overflow:hidden">
        <iframe src="http://mylink" frameborder="0" style="overflow:hidden;height:100%;width:100%" height="100%" width="100%"></iframe>
    </asp:Content>

The width of the iframe does expand to the width of the screen but the height is always something like 100 pixels even though it should be close to 1050.

Browser IE9. How to fix the height problem?
