VectorMapBuilder.Layers(Action<CollectionFactory<VectorMapLayerBuilder>>) Method

Provides access to the client-side layers option that represents a VectorMap layer collection.

Namespace: DevExtreme.AspNet.Mvc.Builders

Assembly: DevExtreme.AspNet.Core.dll

Declaration

public VectorMapBuilder Layers(
    Action<CollectionFactory<VectorMapLayerBuilder>> configurator
)

Parameters

Name Type Description
configurator Action<CollectionFactory<VectorMapLayerBuilder>>

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

Returns

Type Description
VectorMapBuilder

A reference to this instance after the method is called.

Remarks

To configure a VectorMap layer 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 VectorMapLayerBuilder whose methods you can use to configure an item.

@(Html.DevExtreme().VectorMap()
    .Layers(layers => {
        layers.Add(); // call methods to configure a VectorMap layer
        layers.Add();
    })
)
