Hello, Marc,
Thank you for writing.
Currently, RadGanttView doesn't support such kind of functionality. However, we already have a similar issue logged in our
feedback portal. You can track its progress, subscribe for status changes and add your comments on the following link -
feedback item.
Currently, you can delete the link programmatically from the
DataSource.
I hope this information helps. Should you have further questions I would be glad to help.
Regards,
Dess
