FilterBuilderBuilder<T>.CustomOperations(Action<CollectionFactory<FilterBuilderCustomOperationBuilder>>) Method

Provides access to the client-side customOperations option that represents a custom operation collection.

Namespace: DevExtreme.AspNet.Mvc.Builders

Assembly: DevExtreme.AspNet.Core.dll

Declaration

public FilterBuilderBuilder<T> CustomOperations(
    Action<CollectionFactory<FilterBuilderCustomOperationBuilder>> configurator
)

Parameters

Name	Type	Description
configurator	Action<CollectionFactory<FilterBuilderCustomOperationBuilder>>	A function that allows you to add items to the collection.

Returns

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

Remarks

To configure a custom operation 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 FilterBuilderCustomOperationBuilder whose methods you can use to configure an item.

Razor C#

@(Html.DevExtreme().FilterBuilder()
    .CustomOperations(customOperations => {
        customOperations.Add(); // call methods to configure a custom operation
        customOperations.Add();
    })
)
