javascript errors on Bing.com (and other web sites)

[arthurd]

I am trying a simple example of loading http://bing.com in the html placeholder (which is inside a tile view item). I am using Q2 2010 release.

I am always getting error from the bing javascript in function sj_be(_d, "keydown".......

At first I thought if was a generic problem with Bing in iframe but I tried it using the iframe demo at http://www.w3schools.com/tags/tryit.asp?filename=tryhtml_iframe and it worked without error messages.

I get the IE dialog about debugging and if I ignore the error, everything seems to work correctly from that point on.

I have also had javascript errors on Google but they are not as easily reproducable as on bing. I can use other URLs just fine. Seems to be related to certain site javascript incompatibility.

Any ideas?

I forgot another detail that might be relevant.

The html placeholder is in a tile view item but I am using a transition to swap in/out the pages of tile view.

I will try to simplify my test by removing use of transition.

If that works then I will need a way to monitor when the transition is complete and only set the Url in my view model (bound to the SourceUrl) when the transition is complete.

To simplify my test (to eliminate tile view item or transition as problem area), I built a new Silveright 4 project with Telerik Q2 2010. I still get javascript errors on bing.com. I am using IE8.

Here is the entire XAML.

Hi arthurd,

Yes, some sites may have functionality that does not work in an iframe.

I can see the same exception on bing.com even if I place an IFrame over the SL application. It is also present in the w3schools test page:

It is best to show only html that you have control over.

Also if you want to display just rich text, I can suggest using our new RadRichTextBox.

All the best,
