Add an event that can be subscribed to when a user makes a change to a cell.
This might look not so important in many use cases. However, when the add-in takes in data from the worksheets and saves them through API calls, it becomes quite useful for a good user experience. Currently, users would need to click on a button in the add-in that would save all of the rows in one go. However, It would be nice if they don't require to do that and the changes can be saved real-time.
Ahamed, thanks for your feedback! You can use the addFromNamedItem API to add data changed event and listen in on data changes. Refer to https://dev.office.com/reference/add-ins/excel/bindingcollection for more information.
