I think I've found it
...SaveFileDialogForm.ExplorerControl.FileBrowserListView.AllowDrop = False
...SaveFileDialogForm.ExplorerControl.MainNavigationTreeView.AllowDrop = False

Hello, Steve,
The ExplorerControl used in the file dialogs internally uses a RadListView which handles the whole drag and drop operation by its ListViewDragDropService. By using the ExplorerControl.FileBrowserListView property you can access this list view.
As you have already found out setting the ExplorerControl.FileBrowserListView.AllowDrop property to false will disable the whole drop operation to this control.
If you need to control the drop behavior and allow it in certain cases, the PreviewDragOver event of the service allows you to control on what targets the file(s) being dragged can be dropped on.
The whole API of the service is explained here: https://docs.telerik.com/devtools/winforms/telerik-presentation-framework/raddragdropservice
I hope this information helps. If you need any further assistance please don't hesitate to contact me.Regards,
