DataGridBuilder<T>.Columns(Action<CollectionFactory<DataGridColumnBuilder<T>>>) Method

Provides access to the client-side columns option that represents a DataGrid column collection.

Namespace: DevExtreme.AspNet.Mvc.Builders

Assembly: DevExtreme.AspNet.Core.dll

#Declaration

C#
public DataGridBuilder<T> Columns(
    Action<CollectionFactory<DataGridColumnBuilder<T>>> configurator
)

#Parameters

Name Type Description
configurator Action<CollectionFactory<DataGridColumnBuilder<T>>>

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

#Returns

Type Description
DataGridBuilder<T>

A reference to this instance after the method is called.

#Remarks

To configure a DataGrid column 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 DataGridColumnBuilder<T> whose methods you can use to configure an item.

@(Html.DevExtreme().DataGrid()
    .Columns(columns => {
        columns.Add(); // call methods to configure a DataGrid column
        columns.Add();
    })
)
