Edit/delete data in the datagrid

Good morning,

I would like to know if you can help me in this case, please.

I have a datagrid where I bring the user data (name, position and email

To bring this data, I created a collection named userWorkProfile to bring the necessary data from two tables

So far so good… now returning to my datadrid, I need to define the workflow for the UPDATE action

However, when I select the position and name , I can’t identify where it is…

Am I on the correct path?
