Grid - Footer on Deleting rows

Title:

BI{code} ?

I see your https://demo.aspnetawesome.com/GridCrudDemo sample I insert a footer with sum, but if i delete a row the TOT is not recalculated public IActionResult GridGetItems(GridParams g, string search) { search = (search ?? "").ToLower(); var items = Db.Dinners.Where(o => o.Name.ToLower().Contains(search)).AsQueryable(); return Json(new GridModelBuilder<Dinner>(items, g) { Key = "Id", // needed for api select, update, tree, nesting, EF MakeFooter = MakeFooter, GetItem = () => Db.Get<Dinner>(Convert.ToInt32(g.Key)), Map = MapToGridModel }.Build()); } private object MakeFooter(GroupInfo<Dinner> info) { return new { Id = "TOT = " + info.Items.Sum(o => o.Id) }; }

  when you delete a row in our demo `utils.itemDeleted` is called and that function removes the html row `tr`, what you need to do is reload the grid, so that the footer will be recalculated. you can either change `CrudHelpers.InitCrudPopupsForGrid` to use `utils.refreshGrid` instead of `itemDeleted`, or change `utils.itemDeleted` to the same as `utils.refreshGrid`
