CellEndEdit event.

I have a Windows Form view a datagridview in my cobol program. During program execution I am editing the contents of a cell without leaving the cell, i.e. I am not hitting the Enter or Tab key. 
Without leaving the cell, I am pushing a button (like a save button) outside of the datagridview on the same form. But because the CellEndEdit event did not take place, the contents of the cell in question has not changed.
So I want to invoke the CellEndEdit programatically. The following code 
invoke myGrid_CellEndEdit().
is giving me an error because of the missing parameters. Which parameters do I have to put here in the brackets?
