CollectionViewNavigator

The CollectionViewNavigator control allows users to navigate the items or pages in CollectionView components.

To use it, set the navigator's cv property to the CollectionView instance it should control.

To navigate by page, set the byPage property to true. To navigate by item, set it to false.

You can customize the display of the current item/page by setting the navigator's headerFormat property.

import 'bootstrap.css'; import '@grapecity/wijmo.styles/wijmo.css'; import './styles.css'; import { CollectionView } from '@grapecity/wijmo'; import { ComboBox, CollectionViewNavigator } from '@grapecity/wijmo.input'; import { FlexGrid } from '@grapecity/wijmo.grid'; document.readyState === 'complete' ? init() : window.onload = init; function init() { // create the CollectionView let view = new CollectionView(getData(), { pageSize: 5 }); // allow user to change the CollectionView's page size new ComboBox('#cmb-pg-size', { itemsSource: [0, 5, 10], selectedValue: view.pageSize, textChanged: (s) => { view.pageSize = s.selectedValue; } }); // navigate the CollectionView by item (within the current page) new CollectionViewNavigator('#cv-nav', { cv: view, headerFormat: 'Item {currentItem:n0} of {itemCount:n0} (on page {currentPage:n0})' }); // navigate the CollectionView by page new CollectionViewNavigator('#cv-pg', { cv: view, byPage: true, headerFormat: 'Page {current:n0} of {count:n0}' }); // show the data in a grid new FlexGrid('#cv-grid', { itemsSource: view, selectionMode: 'RowRange', showMarquee: true }); // get the data for the CollectionView function getData() { let countries = 'US,Germany,UK,Japan,Italy,Greece'.split(','), names = 'Abe,Bob,Chuck,Dan,Ed,Fred'.split(','), data = []; for (let i = 0; i < 50; i++) { data.push({ id: i, name: names[i % names.length], country: countries[i % countries.length], active: i % 5 != 0, downloads: Math.round(Math.random() * 200000), sales: Math.round(Math.random() * 20000), }); } return data; } }
