AsObservable get count of changed childs

[AlanFloyd]

Hello,

i have implemented with success the AsObservable in my app and it is working perfect. I would like to update the user interface, once all changes of childs are received. Is there an option to get the number of all changes to childs (number of childs that are changed) or will this count be always 1, even when more than 1 child was updated.

Greetings and thanks Dietmar

One option is buffering the changes so you can receive a batch. Buffer returns IObservable<IList>

.AsObservable().Buffer(TimeSpan.FromSeconds(1))
