如何在GridControl中按组数对组进行排序

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 (ie grouping by that column) I want the groups to be sorted by their member count. I have found no source about how to even begin doing that. I am not sure if it is even possible.

What I am getting: (Name of Column is Message)

Message:(Count=2) X

Message:(Count=7) U

Message:(Count=5) Z

What I want:

Message:(Count=7) U

Message:(Count=5) Z

Message:(Count=2) X

Answer 1

I think you should handle the StartGrouping event of the grid (more info here ). Then I think that it is a matter of sorting the grouped rows manually by setting their indexes giving a row's count.
