Namespace: DevExtreme.AspNet.Mvc.Builders

Assembly: DevExtreme.AspNet.Core.dll

Declaration

public TreeListColumnBuilder<T> Buttons(
    Action<CollectionFactory<TreeListColumnButtonBuilder>> configurator
)

Parameters

Name Type Description
configurator Action<CollectionFactory<TreeListColumnButtonBuilder>>

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

Returns

Type Description
TreeListColumnBuilder<T>

A reference to this instance after the method is called.

Remarks

To configure a TreeList column button 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 TreeListColumnButtonBuilder whose methods you can use to configure an item.

@(Html.DevExtreme().Gantt()
    .Columns(columns => {
        columns.Add().Buttons(buttons => {
            buttons.Add(); // call methods to configure a TreeList column button
            buttons.Add();
        });
    })
)
