Answer 1

This code above was wrong!

foreach (DataGridViewRow row in dataGridView1.Rows)
{
    DataGridViewCheckBoxCell cell = row.Cells[0] as DataGridViewCheckBoxCell; 

    // Note: Can't check cell.value for null if Cell is null 
    // just check cell != null first
    //We don't want a null exception!
    if (cell.Value != null)
    {
        if (cell.Value == cell.TrueValue)
        {
           //It's checked!
        }  
    }              
}
