Ajax Binding

The AutoComplete provides support for remote data binding by using a DataSource configuration object. You can configure the AutoComplete to get its data from a remote source by making an AJAX request.

1. Create an action that returns the data as a JSON result.

       public IActionResult Index()
       {
           return View(new ProductViewModel
           {
               ProductID = 4,
               ProductName = "ProductName4"
           });
       }
   
       public JsonResult GetProductsAjax()
       {
           var products = Enumerable.Range(0, 500).Select(i => new ProductViewModel
           {
               ProductID = i,
               ProductName = "ProductName" + i
           });
   
           return Json(products);
       }
   

2. Add the AutoComplete to the view and configure its DataSource to use remote data.

    @model MvcApplication1.Models.ProductViewModel

    @(Html.Kendo().AutoCompleteFor(m => m.ProductName)
        .Filter("contains")
        .DataTextField("ProductName")
        .Placeholder("Select product...")
        .DataSource(source =>
        {
            source.Read(read =>
            {
                read.Action("GetProductsAjax", "Home");
            })
            .ServerFiltering(false);
        })
    )

    <kendo-autocomplete for="products" style="width:100%"
            dataTextField="ProductName"
            placeholder="Select product..."
            filter="FilterType.Contains">
            <datasource type="DataSourceTagHelperType.Custom" server-filtering="false">
                <transport>
                    <read url="@Url.Action("GetProductsAjax", "Home")" />
                </transport>
            </datasource>
    </kendo-autocomplete>
