TreeViewBuilder.Items(Action<CollectionFactory<TreeViewItemBuilder>>) Method

Provides access to the client-side items option that represents a TreeView item collection.

Namespace: DevExtreme.AspNet.Mvc.Builders

Assembly: DevExtreme.AspNet.Core.dll

Declaration

public TreeViewBuilder Items(
    Action<CollectionFactory<TreeViewItemBuilder>> configurator
)

Parameters

Name Type Description
configurator Action<CollectionFactory<TreeViewItemBuilder>>

A function that allows you to add items to the collection.

Returns

Type Description
TreeViewBuilder

A reference to this instance after the method is called.

Remarks

To configure a TreeView item collection, use a multiline lambda expression. In this case, a lambda parameter performs the role of a collection factory, and its Add() method adds a new item to the collection. The Add() method returns TreeViewItemBuilder whose methods you can use to configure an item.

@(Html.DevExtreme().TreeView()
    .Items(items => {
        items.Add(); // call methods to configure a TreeView item
        items.Add();
    })
)
