Provides access to the client-side groupItems option that represents a summary item collection.

Namespace: DevExtreme.AspNet.Mvc.Builders

Assembly: DevExtreme.AspNet.Core.dll

Declaration

public DataGridSummaryBuilder<T> GroupItems(
    Action<CollectionFactory<DataGridSummaryGroupItemBuilder<T>>> configurator
)

Parameters

configurator	Action<CollectionFactory<DataGridSummaryGroupItemBuilder<T>>>	A function that allows you to add items to the collection.

Returns

Type	Description
DataGridSummaryBuilder<T>	A reference to this instance after the method is called.

Remarks

To configure a summary item 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 DataGridSummaryGroupItemBuilder<T> whose methods you can use to configure an item.

Razor C#

@(Html.DevExtreme().DataGrid()
    .Summary(summary => summary
        .GroupItems(groupItems => {
            groupItems.Add(); // call methods to configure a summary item
            groupItems.Add();
        })
    )
)
