Remote Binding
The Telerik UI ListBox for ASP.NET MVC enables you to bind it to a remote data source.
When you use complex data objects, use the DataTextField and DataValueField properties to notify the ListBox about your preferred binding behavior.
@(Html.Kendo().ListBox()
.Name("optional")
.DataTextField("ContactName")
.DataValueField("CustomerID")
.DataSource(source => source
.Read(read => read.Action("GetCustomers", "ListBox")) // Configure the data source for remote data binding
)
.TemplateId("customer-item-template")
.Draggable(draggable => draggable.Placeholder("customPlaceholder"))
.DropSources("selected")
.ConnectWith("selected")
.Toolbar(toolbar =>
{
toolbar.Position(ListBoxToolbarPosition.Right);
toolbar.Tools(tools => tools
.MoveUp()
.MoveDown()
.TransferTo()
.TransferFrom()
.TransferAllTo()
.TransferAllFrom()
.Remove());
})
.BindTo(new List<CustomerViewModel>())
)
@(Html.Kendo().ListBox()

.TemplateId("customer-item-template")
