如何按组在 GridControl 中的计数对组进行排序

Question

While using DevExpress.XtraGrid.GridControl I am trying do the following, When a column is selected and dragged to the upper part of grid (i.e grouping by that column) I want the groups to be sorted by their member count.我什至没有找到关于如何开始这样做的来源。我不确定这是否可能。

我得到了什么：（列的名称是消息）

Message:(Count=2) X

Message:(Count=7) U

Message:(Count=5) Z

我想要什么：

Message:(Count=7) U

Message:(Count=5) Z

Message:(Count=2) X

我认为您应该处理网格的StartGrouping 事件（更多信息here）。然后我认为这是通过设置索引来手动对分组行进行排序的问题。
