Hi Otto,
We regret for the inconvenience caused.
At present “ActionComplete” client side event is used to retrieve only the item with updated values, for updating it to the database, but there is no support to retrieve the information with edited column fields. So we recommend you to use the “EndEdit” client side event for retrieving the information of updated fields. We are planning to implement updated fields, updated records and some additional arguments to the “ActionComplete” client side event in Gantt control.
For this we have already logged feature report “Optimizing client side events in Gantt” regarding this and suggest you to follow up the incident “Update gantt values and save to database” for further reference.
Please let us know if you require further assistance on this.
Regards,
John. R
