Description FieldstrikeMobile 2016-04-20 16:27:11 UTC
A carouselView is essentially a list of items.

Therefore following standard guidelines this control needs to expose a TwoWay "SelectedItem" property.

There is currently an Item property on carouselview which is not bindable and only contains a getter.

This needs to be exposed as a two way bindable property

Yes, we'll work towards that. What would you expect the behavior to be in the case of duplicate Items in the item source? Pick the first one? The closest one to the current position? Always to the left or right of the current position?

@ChrisKing This isnt something I'd considered actually. I'd always presumed that people wouldnt use duplicate items in something like this. In the same way you wouldnt expect people to use duplicate items in a combo box. But I think if this was the case where items were duplicated I would expect it to pick the first one in the item source that matched
