Try this:

C#

private void DataGridView1_CellPainting(object sender, DataGridViewCellPaintingEventArgs e)
       {
           var dgv = (DataGridView) sender;

           if (e.RowIndex < 0)
               return;

           var rowCurrent = ((DataRowView) dgv.Rows[e.RowIndex].DataBoundItem).Row;

           e.CellStyle.BackColor = rowCurrent["yourValue"].ToString() == "0" 
               ? Color.White
               : Color.Red;
       }

Solution 2

Each datagridview has rows and columns. "yourValue" means the datapropertyname of the column you want to check
