Question

Silverlight application doesn’t work on my machine anymore.

Screenshot:

When I run the application the window becomes white. I copied following exception message from IE developer tools console (FF doesn’t work either):

    Code: 4004

I believe that RadChart is causing the issue.

Everything works fine on collegue’s machine.

How can I fix it?

Edit: I think that on the client exception is thrown only when RadChart’s ItemsSource is bound to data source.

Answer 1

Sorry, my bad 😉

Numbers format in ‘Region and Language’ settings was changed (‘,’ and ‘.’)

After format reset RadChart works.
