Description

DataGridView.Sort seems to be implemented via the quick sort algo in DataGridViewRowCollection.RowArrayList.

I would like to be able to sort the DataGridView in a non-destructive (stable) way when changing the sort column (clicking the header to sort). Eg. If I sort on the first column and then sort on the second, the rows remain sorted by column 1 for equal values of column 2.

Contributor guide

Research direction
Investigate the sorting algorithm in DataGridViewRowCollection.RowArrayList and implement a stable sort that preserves previous sort order when changing sort columns.
