AG_E_PARSER_BAD_TYPE error when using DataForm control in Prism/silverlight 3

Question

I'm using prism and SL3, as soon as I drop a DataForm Control in any modules, I get this error:

AG_E_PARSER_BAD_TYPE [Line: 6 Position: 31] at System.Windows.Application.LoadComponent(Object component, Uri resourceLocator) at HelloWorldModule.Views.HelloWorldView.InitializeComponent() at HelloWorldModule.Views.HelloWorldView..ctor()

I don't get this error if I drop the DataForm control in my Shell.xaml, only if I drop in any views in the modules. anyone can shed some light?

Answer 1

You need to add Microsoft.Windows.Controls to your ModuleManifest.xaml..

Answer 2

The latest drop of PRISM suggests that the ModuleManifest is obsolete, so the comment above will not work.

In addition, how can one resolve this AG_E_PARSER_BAD_TYPE error when viewing the XAML in design mode? For me the run-time is fine, but i receive this error when viewing in Visual Studio 2008's design view.

Answer 3

Yes...you need to add reference of the dll. It worked for me.
