Custom Data Binding

You can configure the Telerik UI MultiSelect to use a custom DataSource and, in this way, bind to a ToDataSourceResult instance.

1. Create an action method which renders the view.

   Razor

    public ActionResult Index()
    {
        return View();
    }

2. Create a new action method and pass the Products table as JSON result.

   Razor

    public JsonResult GetProducts([DataSourceRequest] DataSourceRequest request)
    {
        NorthwindDataContext northwind = new NorthwindDataContext();
   
        return Json(northwind.Products.ToDataSourceResult(request));
    }

3. Add an Ajax-bound MultiSelect.

   Razor

       @(Html.Kendo().MultiSelect()
           .Name("productDropDownList") // The name of the MultiSelect is mandatory. It specifies the "id" attribute of the widget.
           .DataTextField("ProductName") // Specify which property of the Product to be used by the MultiSelect as a text.
           .DataValueField("ProductID") // Specify which property of the Product to be used by the MultiSelect as a value.
           .DataSource(source =>
           {
               source.Custom()
                       .ServerFiltering(true)
                       .Type("aspnetmvc-ajax") // Set this type if you want to use DataSourceRequest and ToDataSourceResult instances.
                       .Transport(transport =>
                       {
                           transport.Read("GetProducts", "Home");
                       })
                       .Schema(schema =>
                       {
                           schema.Data("Data") // Define the [data](https://docs.telerik.com/kendo-ui/api/javascript/data/datasource#configuration-schema.data) option.
                               .Total("Total"); // Define the [total](https://docs.telerik.com/kendo-ui/api/javascript/data/datasource#configuration-schema.total) option.
                       });
           })
       )
