Add a setter for the AutoCompleteBox's SelectedItem property.

For example, to use different keys than the default arrow keys to switch from day -> month -> year in DatePicker

Enable drag and drop between cells of different rows in the DataGrid for UWP. Or a way we can develop it ourselfs.

When the DataGrid is grouped, show the column headers in the group header and allow for aggregates like Sum

It should be similar like the RealizedItemsVerticalBufferScale, but to work for the horizontal part of the ViewPort.

Would be great if the TimeBar from WPF would be added to the UWP family. No new features required as the WPF equivalent is rich enough. Just port as is!

Enabled the control to load its ExpandableContent using the x:DeferLoadStrategy="Lazy" attribute.

Ability to export to Excel/PDF from grid. Any idea when this would be available? 

Hi, just wondering - is the source code the the sample UWP demo app available? I'm referring to UI for UWP Demos app that is available in the windows app store.

Available in the R1 2018 release. The code could be found on the following link: 
https://github.com/telerik/UI-For-UWP-Demos

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.
