I have a Property
in my App.xaml.cs called User
that holds the User details.
I have read here that you can't have a dependency property on the App class.
I chose to use App.cs because it is global to the entire program and this is used for access control, but any alternatives are welcome.
Now my question is how can I bind to this property from my UserControls and Windows.
IsEnabled="{Binding Path=User, Converter={StaticResource hasAccessConverter}, ConverterParameter=Mid}"
This obviously only works on a property on the DataContext
. I want to access the property on the App.
Can someone show me an example of the binding to the App.xaml.cs property if I implement INotifyChanged
?
I have read here that you can't have a dependency property on the App class.
Indeed you can't, because Application
doesn't inherit from DependencyObject
. However, it's not necessary : only the target property of a binding needs to be a dependency property.
If you want to bind to a property of your App class, you can do it like that :
IsEnabled="{Binding Path=User, Source={x:Static Application.Current}}"
