Grouping is, at least at this point, a documented limitation of this feature. Dragging rows requires that the grid knows and can use the data type, and grouping effectively changes that (you can read more about this here).
Are there plans to support grouping in the future?
I have a few grids where I need to be able to move rows between groups as well.

The listview does not render the items at all - their entire rendering is in the control of the application developer. This is why such a feature there would have to come from application code (e.g., through a similar library). Thus, I've logged a feature request for a sortable enhancer in blazor, so you can Follow its implementation: https://feedback.telerik.com/blazor/1503723-sortable-widget-enhancer.

I would like to see this supported for re-ordering items in a ListView as well as dragging (removing) items from one ListView on the left and dropping (adding) them to another ListView on the right. We currently use Sortable.JS for this in other projects, but can't find any support for this in Blazor.
