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 Refresh while a previous refresh is still underway. Calling Refresh twice raises the DataChanged event twice.
