❔ Best way to make editable schedule

Looking to make a sort of grid-based schedule in WPF where different resources can have different tasks associated with them at each time slot (time slots are shifts in a day, and there can be variable amount of shifts). What would be the best way to approach this? Ideally this would be interactive, with users able to choose different tasks (via typing into the box or via drop-down menu) and move them around via drag/drop. Not looking for a full solution, just some guidance as to how to proceed.
