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

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.

Razor C#

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