check a checkbox inside a datagridView

I'm having some trouble with adding a value to a dataGridView where I created the cells by hand (not by code) and there is a cell in the format of a checkbox. I'm trying to fill from a database and in the database I have a row contains only 1 or 0 and I need to translate that checked or not checked in the dataGridView Note: the checkbox is already created I only need to check it by code.

Please let me know if you need more info?
