Hide row with specific cell value DataGridView C#

Question

I'm having trouble hiding rows with 0 value in DataGridView.

foreach (DataGridViewRow row in this.taggGrid.Rows)
{
    if (Convert.ToString(row.Cells[4].Value).Equals(0))
    {
        row.Visible = false;
    }
}

The row I want to hide still shows.

                dr.Visible = false;
            }
