Ajax Binding

During the Ajax binding the AutoComplete makes Ajax requests to get the data.

To configure the AutoComplete for Ajax binding to the Northwind Products table by using Linq to SQL:

  1. Make sure you followed all the steps from the introductory article on Telerik UI for ASP.NET MVC.
  2. Create an action method which renders the view.

    public ActionResult Index()
    {
        return View();
    }
    
  3. Create a new action method and pass the Products table as JSON result.

    public JsonResult GetProducts()
    {
        NorthwindDataContext northwind = new NorthwindDataContext();
        return Json(northwind.Products, JsonRequestBehavior.AllowGet);
    }
    
  4. Add an Ajax-bound AutoComplete.

    The ToDataSourceResult() extension method modifies the structure of the result and the AutoComplete is not able to bind to it. In this case, return a simple array of data.

          <%: Html.Kendo().AutoComplete()
              .Name("productAutoComplete") // The name of the AutoComplete is mandatory. It specifies the "id" attribute of the AutoComplete.
              .DataTextField("ProductName") // Specify which property of the Product to be used by the AutoComplete.
              .DataSource(source =>
              {
                 source.Read(read =>
                 {
                      read.Action("GetProducts", "Home"); // Set the Action and Controller names.
                 })
                 .ServerFiltering(true); // If true, the DataSource will not filter the data on the client.
              })
          %>
    
          @(Html.Kendo().AutoComplete()
            .Name("productAutoComplete") // The name of the AutoComplete is mandatory. It specifies the "id" attribute of the AutoComplete.
            .DataTextField("ProductName") // Specify which property of the Product to be used by the AutoComplete.
            .DataSource(source =>
             {
                source.Read(read =>
                {
                     read.Action("GetProducts", "Home"); // Set the Action and Controller names.
                })
                .ServerFiltering(true); // If true, the DataSource will not filter the data on the client.
             })
          )
