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.

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

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

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

3. Add an Ajax-bound MultiSelect.

       @(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.
                       });
           })
       )
   

       <kendo-multiselect name="productDropDownList"
                          datatextfield="ProductName"
                          datavaluefield="ProductID">
          <datasource type="DataSourceTagHelperType.Custom" server-filtering="true">
               <transport>
                    <read url="@Url.Action("GetProducts", "Home")" />
               </transport>
               <schema data="Data" total="Total">
               </schema>
          </datasource>                 
       </kendo-multiselect>
