CollectionView Paging (Vue)

Paging is a common technique for dealing with large collections of data.

The CollectionView class supports client-side paging by default, so you can generate grids and tables that contain only a reasonable amount of data.

To enable paging, set the pageSize property and use the moveToPage method to select the page you want to display.

This example uses Vue.

<template> <div class="container-fluid"> <wj-collection-view-navigator headerFormat="Page {currentPage:n0} of {pageCount:n0}" :byPage="true" :cv="data" /> <wj-flex-grid headersVisibility="Column" :alternatingRowStep="0" :itemsSource="data" /> </div> </template> <script> import "@grapecity/wijmo.styles/wijmo.css"; import "bootstrap.css"; import Vue from "vue"; import { CollectionView } from '@grapecity/wijmo'; import { CollectionViewNavigator } from '@grapecity/wijmo.vue2.input'; import { FlexGrid } from '@grapecity/wijmo.vue2.grid'; new Vue({ el: "#app", data: { data: _getData() } }); function _getData() { // create an array with 1000 data items let countries = 'US,Germany,UK,Japan,Italy,Greece'.split(','); let products = 'Piano,Violin,Flute,Guitar,Cello'.split(','); let data = []; for (let i = 0; i < 1000; i++) { data.push({ id: i, country: countries[i % countries.length], product: products[i % products.length], sales: Math.random() * 10000, expenses: Math.random() * 5000 }); } // create a paged CollectionView with 6 data items per page return new CollectionView(data, { pageSize: 6 }); } </script>
