Verify that the cell is of type DataGridViewCheckBoxCell first...
You also might want to verify that the
DataGridViewCheckBoxCell.TrueValue is not null since it's an object
and not a boolean data type.

foreach (DataGridViewRow row in dataGridView.Rows)
{
if (!row.IsNewRow)
{
if (row.Cells[0].GetType() ==
typeof(DataGridViewCheckBoxCell))
{
if ((bool)
(((DataGridViewCheckBoxCell)row.Cells[0]).TrueValue))
{
return true;
}
}
}
}
