OnClick event in WinForms DataGridView

Question

I use DataGridView in WinForms, and with this piece of code I assign it to columns and values

dataGrid.DataSource = sourceObject;

Only this row contains all the columns and values ​​in the grid. How to handle the onClick event of a specific row or field. I want to edit a specific element in the grid, but I cannot find a way to send the identifier of the element from the event method.

Is there a DataGridViewEventHandler class that I don't understand?

I also tried to add columns manually as buttons, but I did not find a way to assign it to the action onClick method.
