Hello Ivan,
To achieve your requirement you can use the built-in drag/drop feature of RadGridView and DragDropManager to handle the drop in the RadGridView cells. Here are some steps which you can try.

To achieve your requirement you can use the built-in drag/drop feature of RadGridView and DragDropManager to handle the drop in the RadGridView cells. Here are some steps which you can try.
- Enable the drag/drop in RadTreeView. You can do that by setting its IsDragDropEnabled property to True.
- Subscribe to the DragDropManager.Drop event and based on the corresponding data edit the cell content.
- You have two options for the Drop event. You can subscribe it directly to RadGridView and used ParentOfType<T>() method on the argument OriginalSource to get the GridViewCell element and updated it or its DataContext. The second option is to use the CellLoaded event of RadGridView and subscribe the Drop event to each cell separately.
Additionally you can check the DragDropTreeViewToControls and DragDropWithLines SDK example.
I hope this helps.
