HTML5 and Anonymous access in Power BI… or check out the new Demo Gallery

I don’t expect that anyone will be blown away, at least initially, with the new demo gallery now available on the Microsoft Power BI site because to a business user, the content of those demos will look a little difficult to relate to if not a little nonsensical. Zany layouts aside, there is, however, a very significant piece of news to celebrate. Jen Underwood has already mentioned this in her excellent post but now we have a somewhat official, albeit not very conspicuous, evidence that two of the most requested features of the Microsoft BI stack that we have been anxiously awaiting for a very long time are finally becoming available:

  • HTML5 support for Power View
  • Support for Anonymous authentication and ability to expose Power View on a public anonymous site

Try to right click on the demos in the gallery and you will see that the familiar Silverlight menu option is no longer available, instead you will see a normal set of options that show up when you right click on any typical HTML element of the page. If you examine the source code a little bit close you will see <iframe
frameborder=”0″ allowtransparency=”true” scrolling=”no” id=”” style=”width:1024px; height:650px;” src=”″></iframe>
that the HTML5 code is generated inside an IFRAME. Looks like there
are several parameters, that will hopefully be documented soon, that are involved:

  1. – is the main URL
  2. Guestaccesstoken
  3. DocID
  4. Action (Embedview is already well documented)
  5. wdBIPreview

In fact, if you put all of the pieces together, you will be able construct this link

It is good to see the Power BI site to get regular updates, particularly of such great significance. Definitely looking forward to the hopefully soon upcoming documentation for these awesome new features.
