Remarks

When an XAF application needs to display a View, the application calls the ShowView method. To correctly display the View, the ShowView method requires information on the current context in the form of a ShowViewSource object. For this purpose, the ShowViewSource class exposes the following public properties.

SourceAction	If a View has to be displayed as the result of an Action, this property contains reference to the Action’s instance.
SourceController	If a View has to be displayed as the result of an Action, this property contains reference to the instance of the Action‘s Controller.
SourceView	Contains a reference to the View that is represented by the Frame from which the ShowView method is invoked.
SourceFrame	Contains a reference to the Frame from which the ShowView method is invoked.
