 例一：

 
   
  private 
    
  void 
   dataGridView1_RowPrePaint( 
  object 
     sender,   DataGridViewRowPrePaintEventArgs   e)
{
     
  if 
  (e.RowIndex  
  < 
   dataGridView1.Rows.Count  
  - 
  1 
  )
    {
        DataGridViewRow dgrSingle  
  = 
   dataGridView1.Rows[e.RowIndex];
         
  try 
  
        {
             
  if 
  (dgrSingle.Cells[ 
  " 
  列名 
  " 
  ].Value.ToString().Contains( 
  " 
  比较值 
  " 
  ))
            {
                dgrSingle.DefaultCellStyle.ForeColor  
  = 
   Color.Red;
            }
        }
         
  catch 
  (Exception ex)
        {
            MessageBox.Show(ex.Message);
        }
    }
}
 
 

 例二：

 

 
   
  private 
    
  void 
   dataGridView1_CellPainting( 
  object 
   sender,DataGridViewCellPaintingEventArgs e)
{
     
  if 
  (e.RowIndex  
  == 
    
  2 
    
  && 
   e.ColumnIndex 
  > 
    
  = 
  0 
  )
    {
         
  using 
  (SolidBrush brush  
  = 
    
  new 
   SolidBrush(Color.Red))
        {
            e.Graphics.FillRectangle(brush,e.CellBounds);
            e.Handled
