Question

I have a very simple silverlight interface that has a bunch of links on it. Sort of like an old school html area map where different parts take you to different places on the internal network.

I was testing my pages in IE on a development box and was having success redirecting the page using

HtmlPage.Window.Navigate(New Uri("http://mytestbox02/"))

I took a copy of the source over to my laptop where the default browser for VS2010 happened to be Chrome and to my surprise my links did not work. Sometimes I saw it redirect but it mangled up the uri and it ended up being in the form of mytestbox02/ and therefore it didn’t go anywhere but 404 because it was missing the http:// prefix. Sometimes I get an exception. Details of that exception are

System.InvalidOperationException was caught
  Message=SetProperty failed.

  InnerException: 

Silverlight 4.1.10111.0 on both the dev box and my laptop.

Any clue what is going on here? I can’t be fully sure my clients will use IE so I hope there is a fix for this. Or something more cross-compatible that I can use other than window.navigate? I haven’t found anything yet though..

It seems that this may in fact be a Chrome issue – I just spent the day fighting it myself.

You’ll probably need to use some kind of javascript.

HtmlPage.Window.Eval("window.location.href = '<something>';");
//or
HtmlPage.Window.Eval("window.location.reload();");
