I think you should use this:

for (int i = 0; i < dataGridView1.RowCount; i++)
{
    for (int j = 0; j < dataGridView1.ColumnCount; j++) 
    {
        if (dataGridView1.Rows[i].Cells[j].Value == DBNull.Value)
        {
            dataGridView1.Rows[i].Cells[j].Value = "null";
        }
    }
}
dataGridView1.Update();
