My case:
- MVVM
- ListView+Details(custom UserControl)
- List bound to MV.Items (IsSynchronizedWithCurrent=true)
- Details bound to MV.Items.Current
- MV.Items.Count == 100
- about 0.2sec to read details (lazy mode)
When I hold the down arrow on the list, very strange things happen:
- list items order change
- current changes in the random order
- CPU usage drastically increments and eventually all hangs.
I've read some post that one should start the timer or run handler in the background, but I am not able to do that, since all the binding WPF does for me.
Is there some way to instruct the binding in my DetailsControl, to wait a while before accepting CurrentItem? Or should I just resign from the clean solution and write custom code in my MV to handle that?
