javascript - Jquery UI sortable on scrolled webpage -

-

there seems problem jquery ui sortable plugin on scrolled webpage. i'm using reorder table rows (and move them 1 table another). when website scrolled, drag&drop bottom table top table doesn't behave correctly imho. dragged element's placeholder not inserted new table @ bottom position, rather few rows after it. it's 2, 3 rows above. until mouse cursor goes up, it's broken. mouse goes @ least 1 pixel down, gets repositioned , fixed.

this screenshot how works when page not scrolled (on left), , later same page when scrolled bit (right):

enter image description here

code straightforward:

  $( ".sortable tbody" ).sortable({"axis": "y", "cursor": "move", 'tolerance': 'pointer', 'cursorat': { top: 20, left: 20 }, 'scroll': false,         "connectwith": $('.sortable tbody'),         "items" : 'tr:not(.nosort)'      });    $('body').scrolltop(340);

jsfiddle

how can fix this? goal ensure behaves same if webpage not scrolled.

i playing whole day, tried possible parameters of jquery ui, tried digg source code, wasn't successful.

i paid hard cash find out bug is. bugfix one-liner.

-    axis = floating ? "clientx" : "clienty"; +    axis = floating ? "pagex" : "pagey";

i'm going attempt propagate fix jquery-ui sources.

update: took year change should accepted in jquery ui current.

asp.net - 'System.Web.HttpContext' does not contain a definition for 'GetOwinContext' Mystery -

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...

there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.
