Ajax Binding

The MultiColumnComboBox provides support for remote data binding by using a DataSource configuration object. You can configure the MultiColumnComboBox 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();
    }
    
    public JsonResult GetProductsAjax()
    {
        var products = Enumerable.Range(0, 500).Select(i => new ProductViewModel
        {
            ProductID = i,
            ProductName = "ProductName" + i
        });
    
        return Json(products);
    }
    
  2. Add the MultiColumnComboBox to the view and configure its DataSource to use remote data.

        @model MvcApplication1.Models.ProductViewModel
    
        @(Html.Kendo().MultiColumnComboBox()
            .Name("multicolumncombobox")
            .Filter("contains")
            .DataTextField("ProductName")
            .DataValueField("ProductID")
            .Placeholder("Select product...")
            .Columns(columns =>
            {
                columns.Add().Field("ProductName").Title("Product Name").Width("200px")
                columns.Add().Field("ProductID").Title("Product ID").Width("200px");
            })
            .DataSource(source =>
            {
                source.Read(read =>
                {
                    read.Action("GetProductsAjax", "Home");
                })
                .ServerFiltering(false);
            })
        )
