I wanted to use the new caching strategy, but I can't seem to get it working. When RecycleElementAndDataTemplate is used, OnSelectTemplate is getting hit once, hence, returning the same data template for every model instance.

If you run the repro on Android (haven't tested other platforms), all cells are either red or aqua depending on model property. In reality, this should be a mix. Change the strategy in CListView's constructor to RecycleElement instead and observe that templates are assigned correctly.

I forgot to add HasUnevenRows = true; to the listview, so please add that while running the project. Also, I'd like to see an automated UI test if possible.
Comment 2 adrianknight89 2017-11-19 05:02:29 UTC
Closing this after reading PR #1085 as it was clear that OnSelectTemplate is triggered once per item type.
