Posted 7 August 2017, 8:11 am ESTI have a datagrid with itemsource bound to an observable collection.
If the user uses the grouping feature, and collapses 1 (or more) groups..
But in the background (on timer) we have newer records arriving in to our collection..
The datagrid will always refresh with all groups expanded.
I need a way to remember which group values are collapsed, and after each refresh (to itemsource) I can re-collapse the correct entries (assuming they still exist of course).
This person also had a similar question:
Any tips/ suggestions (or can it be done)?
Thanks in advance.
