silverlight content not working in iframe

Question

I have an iframe inside an ASPX page like so:

<iframe id="mapFrame" name="mapFrame" src="project/visioMap.htm" frameborder="0" width="100%" height="900px" runat="server" />

The project directory holds Web page content exported by Visio. I want to embed this content into the .NET Website without altering any of the content exported by Visio (ie. *.htm, *.js, *.xaml). This is why I am trying to embed using the iframe tag.

However, when the page is loading, it crashes with the error:

TypeError: parent.parent.FindShapeXML is not a function
var shapeNode = parent.parent.FindShapeXML (pageID, shapeID); // in a *.js file

This error is in a *.js file exported by Visio, but like I said, I don't want to edit any of the files exported by Visio. If I just open visioMap.htm, everything works fine, so an iframe pointing to it should work fine by default.

Apparently, parent.parent has a different meaning when I open visioMap.htm (which has a with 2 frame) directly in the browser, and when I open visioMap.htm indirectly in the browser via an iframe.

Was it helpful?

Solution

Inside Visio "Save as Web" settings dialog has an option "Host in Web page".

enter image description here

By default, its value is "None". You can select here a web page, into which you would like to embed published content. Then it will be placed into <iframe> on this page. Alternatively, select "Basic" to have basic web page generated with <iframe> in it holding published content. This page HTML is as follows:

<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
        <title></title>
    </head>
    <iframe src="[Your visio file name]_main_2.htm" width="100%" height="100%" frameborder="1" scrolling="auto">
        <!-- No iframesupport --> 
    </iframe>
</html>

You can use this page directly or point your <iframe> to "[Your visio file name]_main_2.htm" referenced on this page.
