Source Provider. Refresh Method
Initiates a refresh operation to the underlying data model. The result is returned on the Data property.
public: void Refresh();
public void Refresh ();
member this.Refresh : unit -> unit
Public Sub Refresh ()
A refresh operation is typically asynchronous, a DataChanged event is raised when the Data property assumed a new value. If the refresh operation fails, the Data property is set to
null; the Error property is set with the error exception. The application can call Refresh while a previous refresh is still underway. Calling Refresh twice raises the DataChanged event twice.
