ALV Event for data input

I have an internal table . One of the fields can take input in the ALV grid using ABAP objects.

When the user enters a value in this field , I would like to capture the values in all the cells of all the fields that are adjaccent to this editable field.

I think I will have to use data_changed event . The SLIS examples are a bit complex, If there is a simpler example to show how this can be done , it will be great.
