I am afraid RadListView currently does not support client-side drag-and-drop functionality. You can consider using RadDockZones and RadDocks instead:

We are not able to provide an exact estimate at this point, however this feature will be considered for the next major versions of the control. Best regards, Sebastian the Telerik team
