ListView: Expose setter for SelectedItem property and implement it, so that setting this property applies the corresponding style to the selected item. Declined: The SelectedItem property has public setter. Setting it makes the style be applied as expected on the item.
Declined: Currently UWP does not have an ImageEditor control. On the following link you can find a feature request where you can vote for introducing such a control and track its status: https://feedback.telerik.com/Project/167/Feedback/Details/201118-new-control-image-editor-port-to-uwp
I think that will be a very good feature. Just create a chart control available over this platform. A chart control like UI for Silverlight will be a fantastic one.
