Configure a DevExtreme CustomStore for DataGrid by defining load, update, and insert functions that return Promises. Ensure you implement byKey support for lookup columns and assign a mandatory key field to prevent silent failures during editing.

DevExtreme DataGrid editing and selection fail silently when the underlying store configuration is missing a mandatory key field. Assigning the key property in your ArrayStore, CustomStore, or ODataStore ensures proper row tracking and CRUD execution.

DevExtreme loadMode controls where paging, sorting, and filtering occur. Client-side loadMode processes all raw data locally in the browser, while server-side loadMode delegates these heavy operations to the backend via remote parameters.

Yes, DevExtreme DataSource fully supports ODataStore configuration across Angular, React, Vue, and jQuery. This allows seamless server-side data processing, remote filtering, and CRUD operations within your chosen JavaScript framework.

Fix broken DevExtreme data layer configurations by ensuring all CustomStore functions properly return Promises and verifying correct API usage. Enforce appropriate loadMode selection and key assignment to resolve incorrect data binding.

ArrayStore and LocalStore are limited to client-side data processing, meaning all paging, sorting, and filtering execute locally in the browser. They are not suitable for large datasets requiring remote server-side operations or remote CRUD execution.
