DevExtreme provides the CustomStore UI component to load and edit data from a custom data source. In this demo, the CustomStore fetches data from a custom remote server and displays it in the DataGrid.
The communication between the CustomStore and the server is organized as follows:
Each setting has information about a data operation (sorting, filtering, etc.) and is present only if this operation is declared as remote in the DataGrid's remoteOperations property. If your server does not support a certain operation, do not declare it as remote to perform it on the client.
For more information about the communication between the client and server in DevExtreme, refer to the following help topic: Server-Side Data Processing.
If your server does not support any data operations, set remoteOperations to false and implement the load function as described in the following help topic: Client-Side Data Processing.
