ODataCollectionView

Wijmo includes an ODataCollectionView class that extends CollectionView to provide support for OData sources.

OData is an OASIS standard that defines a set of best practices for building and consuming RESTful APIs.

To use the ODataCollectionView class, create a new instance passing the URL of the data service, the name of the table you want to access, any optional parameters such as the fields you want to retrieve and whether you want filtering, sorting, and paging to be performed on the server or on the client.

import 'bootstrap.css'; import '@grapecity/wijmo.styles/wijmo.css'; import './styles.css'; import { ODataCollectionView } from '@grapecity/wijmo.odata'; import { FlexGrid } from '@grapecity/wijmo.grid'; import { FlexGridFilter } from '@grapecity/wijmo.grid.filter'; document.readyState === 'complete' ? init() : window.onload = init; function init() { // get customer list from Northwind OData service var url = 'https://services.odata.org/Northwind/Northwind.svc'; var customers = new ODataCollectionView(url, 'Customers', { sortOnServer: true, filterOnServer: true }); // show the data on a grid var itemCountElement = document.getElementById('itemCount'); var theGrid = new FlexGrid('#theGrid', { itemsSource: customers, isReadOnly: true, loadedRows: function () { itemCountElement.innerHTML = theGrid.rows.length + ' items'; } }); // add a filter to the grid var f = new FlexGridFilter(theGrid); }
