Get ListBox Items OnPost Event

[Mark]

I am new to ASP.Core. How do I get the selected items from the "selected" ListBox on the OnPost event?

 

  @(Html.Kendo().ListBox()

        .Name("optional")

        .Toolbar(toolbar =>

        {

            toolbar.Position(ListBoxToolbarPosition.Right);

            toolbar.Tools(tools => tools

                .MoveUp()

                .MoveDown()

                .TransferTo()

                .TransferFrom()

                .TransferAllTo()

                .TransferAllFrom()

                .Remove()

            );

        })

        .ConnectWith("selected")

        .DataTextField("PlayerId")

        .DataTextField("Name")

        .Draggable(true)

        .DataSource(ds => ds.Ajax()

        .Read(r => r.Url("/League/PreDraftPage?handler=Read").Data("forgeryToken"))

)

    )

        @(Html.Kendo().ListBox()

        .Name("selected")

              .Toolbar(toolbar =>

        {

            toolbar.Position(ListBoxToolbarPosition.Right);

            toolbar.Tools(tools => tools

                .MoveUp()

                .MoveDown()

          );

        })

        .DataTextField("PlayerId")

        .DataTextField("Name")

        .BindTo(Model.LeaguePreDraftList)

        .Selectable(ListBoxSelectable.Multiple)

public void OnPost()
   {
       Guid leagueId;
       List<LeaguePreDraftViewModel> listModel;


       if (ModelState.IsValid)//save the data
       {
           var name = Request.Form["selected"];
           listModel = LeaguePreDraftList;
       }
       //leagueId = new Guid(id);
       //get data from page

   }

Hello Mark,

To access the selected items of a ListBox the select() method can be used:

• https://docs.telerik.com/kendo-ui/api/javascript/ui/listbox/methods/select

Please take a look at the following Forum thread addressing this scenario: Passing data to the controller for 'selected' ListBox.

Let me know if this helps.
