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.

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