.net - LINQ Update database sort order against a dynamic list -

-

i have database table sortorder column. display list user , use jquery resort list, save server.

after reorder list new list in correct order of ids in database table.

i need way update new sort order database. want query database custom sort order based off list of ids user. can step through list , increment sort order 0.

bonus points code in vb, although c# fine too.

thanks!

you can't store sort order in database unless have sort order field in datatable (or association sort order table stores original table's field fk). if have field in linq query do, orderby(x=>x.sortorder)

so have database record projection 

   public class objectfromdb{         int id{get;set;}         int sortorder{get;set;}    }

when iqueryable<objectfromdb> queryable , int[] newsortorder , this:

     var oldsortedlist = queryable.orderby(x=>x.sortorder).tolist()      foreach(var i=0;i<oldsortedlist.count;i++;){         oldsortedlist[i].sortorder = newsortorder[i];      }      datacontext.submitchanges();

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...
