Hello, Bernhard,
Note that RadDiagramToolbox is a derivative of RadListView. Hence, it handles the whole drag and drop operation by its ListViewDragDropService. It provides a convenient public API that can be useful for handling any moment of dragging a shape from the RadDiagramToolbox to the RadDiagram.
Please refer to the following help articles which will get you familiar with the API that you can use:
https://docs.telerik.com/devtools/winforms/controls/listview/drag-and-drop/listviewdragdropservice
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.
