Please help my question

Datagridview Cell Backcolor formatting

当使用CellFormatting事件时，您不必遍历所有行，因为该事件将为您提供正在修改的单元格的ColumnIndex和RowIndex。只需格式化需要格式化的单元格:

void dgv_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e) {
  if (e.Value != null) {
    if (dgv.Columns[e.ColumnIndex].Name == "kesim" | 
        dgv.Columns[e.ColumnIndex].Name == "torna" ) {
      if (e.Value.ToString() == "True") {
        e.CellStyle.BackColor = Color.Green;
      } else {
        e.CellStyle.BackColor = Color.Red;
      }
    }
  }
}
