Hi Marco,
Thanks for using Syncfusion products.
Currently we don’t have support for adding task via grid. We
have considered this as feature request and will implement in any of our
upcoming release.
However, task/child-task can be added dynamically through
button click and we have prepared a sample for it please download from below
location.
Please let us know if you require further assistance on
this.
Regards,
Suresh S
