c# – 在DataGridView中对行进行分组

您可以尝试使用垂直单元格合并的MSFlexGrid MergeCells属性的功能,而不是本文第 DataGridView Grouping in C#/VB.NET: Two Recipes条中所述的行分组.在此示例中,属于组的行使用垂直合并的单元格可视地连接 – 而不是使用传统的水平组行.

protected override void OnCellPainting(DataGridViewCellPaintingEventArgs args)
{
  base.OnCellPainting(args);

  args.AdvancedBorderStyle.Bottom =
    DataGridViewAdvancedCellBorderStyle.None;

  // Ignore column and row headers and first row
  if (args.RowIndex < 1 || args.ColumnIndex < 0)
    return;

  if (IsRepeatedCellValue(args.RowIndex,args.ColumnIndex))
  {
    args.AdvancedBorderStyle.Top =
      DataGridViewAdvancedCellBorderStyle.None;
  }
  else
  {
    args.AdvancedBorderStyle.Top = AdvancedCellBorderStyle.Top;
  }
}
