GridChooseColumns in .NET, Core could not find property (key)

Title:

BI{code} ?

I follow your http://demo.aspnetawesome.com/GridChooseColumnsDemo demo for setting columns server side (with entity framework core and .net core 2) I made a sample with 2 grids 1 "normal" and 1 with server side column setting, this a source about second: public ActionResult Dyn2GetItems(GridParams g) { var columns = new[] { new Column { Bind = "Id", Width = 70, Sortable = true, Order = 1 }, new Column { Bind = "LoginName", Sortable = true, Order = 2 } }; //first load if (g.Columns.Length == 0) { g.Columns = columns; } var gridModel = new GridModelBuilder<LoginLogEntity>(db.LoginLogs.AsQueryable(), g) { Map = o => new { o.Id, o.LoginName} }.Build(); return Json(gridModel); } view: @(Html.Awe().Grid("GridChooseColumns") .Url(Url.Action("Dyn2GetItems", "RegistryGrid")) .Persistence(Persistence.Session) .ColumnsPersistence(Persistence.Session) .ShowGroupBar(true) .SendColumns(true)) in second grid when click a column to order give me this error : "Could not find property [loginName] on type [LoginLogEntity]. Make sure you specify Key and Column.Bind correctly." (why search [loginName] with l in lowercase ?) PS: if I run the same project in a MVC5 project run correctly

  I can't see anywhere in your code the `Key` being set, however since you're mentioning that this works in MVC5 and in .net core you're asking about lowercase, I'm guessing that the problem might be this: https://github.com/aspnet/Mvc/issues/4283 In asp.net core by default json serialisation will transform properties to camelCase instead of leaving them as they are. in the controller you should be able to set `g.Key` you can also try this: services .AddMvc() .AddJsonOptions(options => options.SerializerSettings.ContractResolver = new DefaultContractResolver());
