DiagramMainToolbarBuilder.Commands(Action<CollectionFactory<DiagramCustomCommandBuilder>>) Method

Provides access to the client-side commands option that represents a command collection.

Namespace: DevExtreme.AspNet.Mvc.Builders

Assembly: DevExtreme.AspNet.Core.dll

#Declaration

C#
public DiagramMainToolbarBuilder Commands(
    Action<CollectionFactory<DiagramCustomCommandBuilder>> configurator
)

#Parameters

Name Type Description
configurator Action<CollectionFactory<DiagramCustomCommandBuilder>>

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

#Returns

Type Description
DiagramMainToolbarBuilder

A reference to this instance after the method is called.

#Remarks

To configure a command 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 DiagramCustomCommandBuilder whose methods you can use to configure an item.

@(Html.DevExtreme().Diagram()
    .MainToolbar(toolbar => toolbar
        .Commands(commands => {
            commands.Add(); // call methods to configure a command
            commands.Add();
        })
    )
)
