DataGridView detect cell value change (checkbox)-CodePudding

I have a DataGridView with a list<> (global variable) as datasource, the list is a list of a self made user data type. The first value in the UDT is a boolean so it shows a checkbox in the DataGridView.

When I check/uncheck a checkbox the boolean value choud be changed in the list<>.

It works with the following code, but it loops through every row and checks the checkbox

private void dgvObjecten_CellContentClick(object sender, DataGridViewCellEventArgs e)
    {
        for (int i = 0; i < dgvObjecten.Rows.Count; i  )
        {
            Dig1Objecten[i].Import = (bool)dgvObjecten.Rows[i].Cells["Import"].Value;
        }
        
        //refresh DataGridView
        dgvObjecten.DataSource = Dig1Objecten;

    }

Is there a way to get the row number of the checkbox that gets changed so it doesn't have to loop through all rows every time 1 checkbox is changed?
