Hi again, I get a XamlException with error AG\_E\_PARSER\_BAD\_TYPE whenever I use a Grid control inside the Xaml (even with an Expression Blend generated Xaml file). Is the Grid control currently supported when working with IronRuby ? – Thibaut ---

You need to change the namespace of the xaml file probably. Expression blend generates xaml for WPF not Silverlight. I used the grid control in my digg client… so i guess it works fine 🙂 On Thu, Apr 10, 2008 at 10:11 AM, Thibaut Barrère [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid) ---

Hi, the root element had x:Class set incorrectly to x:Class=“GridSample.Page”. Chaning it to “System.Windows.Controls.Grid” solved the issue. thanks! – Thibaut 2008/4/10, Jimmy S. [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid): ---

Are you using the Blend 2 Preview for Silverlight? If not, grab it from [Silverlight.net](http://Silverlight.net). If you are, then can you send me what your XAML looks like? I suspect that the root element of your XAML has x:Class set incorrectly for Ruby. If Grid is your root … app.xaml \ app.rb System::Windows::Application.current.load\_root\_visual Grid.new, “app.xaml” ~js From: removed\_email\_address@domain.invalid [[mailto:removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid)] On Behalf Of Ivan Porto Carrero Sent: Wednesday, April 09, 2008 3:18 PM To: removed\_email\_address@domain.invalid Subject: Re: [Ironruby-core] AG\_E\_PARSER\_BAD\_TYPE when using Grid You need to change the namespace of the xaml file probably.

Great! In general, make sure that the x:Class of your XAML matches the type of the first argument you pass into load\_root\_visual. ~js
