Question

I want to embed my web application inside Sharepoint as a web part. This works great on IE8, IE9 and Firefox – but when I open the page with IE7 I can see only a blank (white) IFrame although the inner content has been loaded. The same webapp opened without the Iframe works perfect – also in IE7.

Same for IE8/IE9 with the META tag:

<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" />

I also can click with the right mouse button on the white area and can display the source code of the page embedded in the IFrame.

My IFrame is embedded like this:

<iframe title="WebApp" frameBorder="0" id="MSOPageViewerWebPart_WebPartWPQ2" style="z-index: 1000" name="MSOPageViewerWebPart_WebPartWPQ2" width="1200px" 
height="1200px" src="http://webapps/app1/beta.webapp.aspx?ContentAreaHeight=669px" ddf_src="http://webapps/app1/beta.webapp.aspx?ContentAreaHeight=669px"
<div class="UserGeneric">No IFRames supported.</div></iframe>

In Sharepoint it makes no difference if I embed the IFrame manually with the Content Editor webpart or with the Page Viewer webpart.

Can anyone help me?

Changed CSS style in IFrame page:

html {
  height: 100%; <= removed this line
}

… then it worked again
