  • VectorMapBuilder.Annotations(Action<CollectionFactory<VectorMapAnnotationConfigBuilder>>) Method

    Specifies the annotation collection. Mirrors the client-side annotations object.

    Namespace: DevExtreme.AspNet.Mvc.Builders

    Assembly: DevExtreme.AspNet.Core.dll

    Declaration

    public VectorMapBuilder Annotations(
        Action<CollectionFactory<VectorMapAnnotationConfigBuilder>> configurator
    )

    Parameters

    Name Type Description
    configurator Action<CollectionFactory<VectorMapAnnotationConfigBuilder>>

    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 annotation 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 a VectorMapAnnotationConfigBuilder object whose methods you can use to configure an item.

    @(Html.DevExtreme().VectorMap()
        .Annotations(annotations => {
            annotations.Add(); // call methods to configure a VectorMap annotation
            annotations.Add();
        })
    )
    

    Refer to Nested Options and Collections for more information.
