Hi,
Silverlight does not support binding against static classes. One thing you
could do is something like this:
Create a simple binding helper class that implements INotifyPropertyChanged,
and with one Bool property.
Then create a app level resource like this:
<Application.Resources>
</myapp:BindingHelper x:Key="bindingHelper" />
</Application.Resources>
Then in your App_Startup, you can fetch out your InitParam set through HTML
when initializing your app. Then do this in App_Startup:
((BindingHelper)Resources["bindingHelper"]).IsVisible =
Convert.ToBoolean(e.InitParam["myInitParam"]);
Then where ever you need to hide/show stuff in your app you can use standard
binding.
<Button Enabled="{Binding Path=IsVisible, Path={StaticResource
bindingHelper}}" />
See you in Sydney!
Cheers,
Jonas
