Server Binding

Local data is the data that is available on the client when the MultiColumnComboBox is initialized.

You can bind the MultiColumnComboBox locally on the server by passing the appropriate collection to the component's BindTo() method.

1. Pass the data to the view through ViewData.

   public ActionResult Index()
   {
       ViewData["products"] = GetProducts();
   
       return View(new ProductViewModel
       {
           ProductID = 4,
           ProductName = "ProductName4"
       });
   }
   
   private static IEnumerable<ProductViewModel> GetProducts()
   {
       var products = Enumerable.Range(0, 2000).Select(i => new ProductViewModel
       {
           ProductID = i,
           ProductName = "ProductName" + i
       });
   
       return products;
   }
   

2. Add the MultiColumnComboBox to the view and bind it to the data that is saved in the ViewData.

       @model MvcApplication1.Models.ProductViewModel
   
       @(Html.Kendo().MultiColumnComboBoxFor(m => m.ProductID)
           .DataValueField("ProductID")
           .DataTextField("ProductName")
           .Columns(columns =>
           {
               columns.Add().Field("ProductName").Title("Product Name").Width("200px")
               columns.Add().Field("ProductID").Title("Product ID").Width("200px");
           })
           .BindTo((System.Collections.IEnumerable)ViewData["products"])
       )
