How do we do idle time processing in WPF application?

Question

Is there a way to do idle time processing in WPF application equivalent to OnIdle event in MFC?

Answer 1

You can dispatch a task (using the Dispatcher in the normal way) with a DispatcherPriority of ApplicationIdle, which will only be executed when the application is idle. Sample code:

DispatcherPriority priority = DispatcherPriority.ApplicationIdle;    
Application.Current.Dispatcher.BeginInvoke(priority, action);
