How do you tell if a cell in DataGridView is empty?

foreach (DataGridViewRow r in theTableDataGridView.Rows)
{
richTextBox1.Text += r.Cells[1].Value.ToString() + " " + r.Cells[2].Value.ToString() + "\n";
if (r.Cells[3].Value.ToString() == null) { return; }
else { richTextBox1.Text += r.Cells[3].Value.ToString() + "\n" ; }

This doesnt work... ToString().Trim() does not work... I just can not figure it out.. in the database the default value is .

I just can not figure it out... Thanks in advance!

foreach (DataGridViewRow r in theTableDataGridView.Rows)
{ 
  richTextBox1.Text += string.Format("{0} {1}\n", r.Cells[1].Value.ToString(), r.Cells[2].Value.ToString());
  if (DBNull.Value == r.Cells[3].Value) 
    return; 
  else  
    richTextBox1.Text += string.Format("{0}\n", r.Cells[3].Value.ToString());
}
