c# - DataGridView Selected Row Move UP and DOWN -

how can allow selected rows in datagridview (dgv) moved or down. have done before listview. unfortunetly, me, replacing dgv not option (curses). way, dgv datasource generic collection.

the dgv has 2 buttons on side, yes, & down. can point me in right direction. have code used listview if it'll (it did not me).

if programatically change ordering of items in collection, dgv should reflect automatically.

sloppy, half-working example:

list<myobj> foo = dgv.datasource; int idx = dgv.selectedrows[0].index; int value = foo[idx]; foo.remove(value); foo.insertat(idx+1, value) 

some of logic may wrong, , may not efficient approach either. also, doesn't take account multiple row selections.

hmm, 1 last thing, if you're using standard list or collection isn't going go smoothly. list , collection on't emit events dgv finds useful databinding. 'burp' databinding every time change collection, better solution use system.componentmodel.bindinglist. when change ordering of bindinglist dgv should reflect change automatically.
