Hi, 

I am trying to disable the drop inside option in a RadGanttView but for now I have found no solution ?

Hello Raphaël,

Could you please clarify what is you exact scenario? If you wish to disable the drag&drop from and to the RadGanttView we have a great example demonstrating how to achieve that available in our QSF Locking Functions example. Also you can take a look at the following article from our help documentation that provide more detailed information about RadGanttView's custom DragDropBehavior:
http://docs.telerik.com/devtools/silverlight/controls/radganttview/features/drag-and-drop/dragdrop-custom-behaviors

Hope this helps.
