Hello,

Ctrl Key + drag and drop does copying of the node.
How can I prevent this?
Thanks and Regards,

The GoXamIntro.pdf section about User Permissions covers this.
The easy answer is to set Diagram.AllowCopy=“False” or AllowInsert=“False”, but I don’t know if that would meet your application’s requirements.

If you do still need to allow copying and/or insertion (for example, to support copy and paste), and if you only want to disable that particular functionality, you need to customize the DraggingTool.
If you are not dealing with Windows drag-and-drop, you can override MayCopy to return false.
If you are dealing with Windows drag-and-drop, you can override MayCopyInternal and/or MayCopyExternal, depending on the situations you want to handle.
