dxDataGrid - How to implement a custom store with CRUD operations

The dxDataGrid binding using a CustomStore help topic and the A custom data source does not apply paging, filtering, sorting and grouping article describe how to implement a custom data source that loads data for a dxDataGrid . This example demonstrates how to make a custom store for the dxDataGrid widget manipulate data. For this purpose, we need to implement the insert, update and remove methods in our custom store. Each of these methods will be called automatically by the widget. 

The insert method accepts a parameter that contains values for a new item. The update method accepts two parameters: the first one is a key value of the editing row, and the second one contains values of modified data fields. The remove method accepts a parameter that contains a key value of the deleted row. When a method is called, we need to send a corresponding request to our data service and pass the required parameters. We use jQuery.ajax for sending requests to our data service. This example can be tested with a data service from How to implement the Rest service based on an ASP.NET WebAPI application.
