Description

The Telerik UI for ASP.NET MVC DropDownTree supports local data binding and you can display local data in the component.

To implement local data binding, you need to return a collection (list) of objects from the Controller to the View, for example, by saving that collection in a Model field, and then load the data in the DropDownTree.

The current example demonstrates two approaches for binding the DropDownTree to local data:

  • (Default) Using inline data—An IEnumerable of DropDownTreeItemModel is stored in a ViewBag and passed to the BindTo() method. The DropDownTreeItemModel has an Items field that holds the child nodes (it is a List property). If a given node has items, the Expand icon will be visible.
  • Mapping Model properties—An IEnumerable of a specified Model, for example, CategoryItem, is stored in a ViewBag and passed to another overload of the BindTo() method: the first argument is an IEnumerable of a Model, and the second is the action, which creates a hierarchy of items by using the specified mappings. For example, the child nodes will be bound to the SubCategories property, and the CategoryItem Model properties will be mapped to DropDownTreeItem properties.

Additional Apps

This DropDownTree example is part of a unique collection of hundreds of ASP.NET MVC demos, with which you can see all Telerik ASP.NET MVC components and their features in action. View the source code of the demos from the library or directly adapt, and edit them and their theme appearance in the ThemeBuilder.
