DataGridView How to disable automatic sorting after clicking sort Finish

Summary: Disable sorting after clicking DataGridView columnheader,prevent databound DataGridView from sorting while editing!

problem: I have a databound DataGridView in a WinForms which the user may has sorted by a column. The problem is this:after the user leaves a row after editing a cell in the sorted column, the row is immediately re-sort Ed. This is very disorienting for users and makes editing groups of rows together impossible.

Solution: re-databound When the user start editing, run program, or sorted finish, to does that can disable automatic R E-sorting.ting after a initial sort and then only sort again when the user requests it.
