Namespace: DevExtreme.AspNet.Mvc.Builders

Assembly: DevExtreme.AspNet.Core.dll

Declaration

    Action<CollectionFactory<DiagramToolboxGroupBuilder>> configurator
)

Parameters

Name	Type	Description
configurator	Action<CollectionFactory<DiagramToolboxGroupBuilder>>	A function that allows you to add items to the collection.

Returns

Type	Description
DiagramToolboxBuilder	A reference to this instance after the method is called.

Remarks

To configure a toolbox group 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 DiagramToolboxGroupBuilder whose methods you can use to configure an item.

Razor C#

@(Html.DevExtreme().Diagram()
    .Toolbox(toolbox => toolbox
        .Groups(groups => {
            groups.Add(); // call methods to configure a toolbox group
            groups.Add();
        })
    )
)
