Thank you for writing.
You can achieve sorting by DisplayMember
by setting the DisplayMemeberSort
property of the columns to true. Please note that his functionality is currently supported only for bound grids. At this link
we have a request to support this functionality in unbound mode. Feel free to add your vote for it, if you find it useful.
I hope that you find this information helpful. Should you have any other questions, do not hesitate to contact us.
