Initiates a refresh operation to the underlying data model. The result is returned on the Data property.
Assembly: WindowsBase (in WindowsBase.dll)
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 a null reference (Nothing in Visual Basic); the Error property is set with the error exception. The application can call while a previous refresh is still underway. Calling twice raises the DataChanged event twice.
