Question

I’m looking to create a custom version of UpdateSourceTrigger that I can use with my binding. I don’t know if this is possible, or if instead, I’d need to just create my own binding class. What I’m looking for is, instead of LostFocus or PropertyChanged, have something where it will update the source after some specified time limit.

I found this, but I don’t know if there’s a better way (one of the comments mentioned some memory leaks with the implementation).

Any ideas?

I wouldn’t bother doing this at the binding level, but would instead manifest it in my view model. When the property changes, restart a DispatcherTimer. When the timer expires, kick off your logic. It’s that simple.
