Hello Steve,

You can use the IsDropAllowed property of RadTreeViewItem. In a data-bound scenario you have to use container bindings to set the IsDropAllowed property. More information on hierarchical data and container bindings you can find here. I've also attached a sample project that demonstrates one possible solution to your scenario. Have a look at it and let me know if you have further questions or comments.

All the best,
