Grouping (Vue)

The grid supports grouping via the source CollectionView. Group the data by one or more properties by adding GroupDescription objects to the grid's collectionView.groupDescriptions. You may also want to hide the columns that are being grouped on in order to avoid showing redundant data.

This example uses Vue.

<template> <div class="container-fluid"> <p>This example groups the data by country and by product:</p> <wj-flex-grid :itemsSource="gridData" :initialized="initializeGrid"></wj-flex-grid> <p> This example groups the data by country and product, and hides those columns to achieve a cleaner appearance: </p> <wj-flex-grid :itemsSource="hideColsGridData" :initialized="initializeHideColsGrid"> <wj-flex-grid-column :binding="'country'" :header="'Country'" :visible="false"></wj-flex-grid-column> <wj-flex-grid-column :binding="'product'" :header="'Product'" :visible="false"></wj-flex-grid-column> <wj-flex-grid-column :binding="'downloads'" :header="'Downloads'" :width="'*'"></wj-flex-grid-column> <wj-flex-grid-column :binding="'sales'" :header="'Sales'" :width="'*'"></wj-flex-grid-column> <wj-flex-grid-column :binding="'expenses'" :header="'Expenses'" :width="'*'"></wj-flex-grid-column> </wj-flex-grid> </div> </template> <script> import "@grapecity/wijmo.styles/wijmo.css"; import "bootstrap.css"; import Vue from "vue"; import "@grapecity/wijmo.vue2.grid"; import * as wjcGrid from "@grapecity/wijmo.grid"; import "@grapecity/wijmo.vue2.grid.filter"; import * as wjcCore from "@grapecity/wijmo"; import * as wjcGridFilter from "@grapecity/wijmo.grid.filter"; import "@grapecity/wijmo.vue2.grid.grouppanel"; let App = Vue.extend({ name: "app", data: function() { return { products: ["Phones", "Computers", "Cameras", "Stereos"], countries: ["US", "Germany", "UK", "Japan", "Italy", "Greece"], gridData: null, hideColsGridData: null, }; }, methods: { initializeGrid: function(grid) { grid.select(new wjcGrid.CellRange(0, 0), true); }, initializeHideColsGrid: function(hideColsGrid) { setTimeout(() => { hideColsGrid.select(new wjcGrid.CellRange(0, 2), true); }); }, getData: function() { // generate some random data let data = []; for (let i = 0; i < 200; i++) { data.push({ id: i, country: this.countries[i % this.countries.length], product: this.products[i % this.products.length], downloads: Math.round(100 + Math.random() * 10000), sales: Math.random() * 10000, expenses: Math.random() * 5000 }); } return data; } }, created: function() { var dataSource = this.getData(); this.gridData = new wjcCore.CollectionView(dataSource, { sortDescriptions: ["country", "product"], groupDescriptions: ["country", "product"] }); this.hideColsGridData = new wjcCore.CollectionView(dataSource, { sortDescriptions: ["country", "product"], groupDescriptions: ["country", "product"] }); } }); new Vue({ render: h => h(App) }).$mount("#app"); </script> <style> .wj-flexgrid { max-height: 250px; margin: 10px 0; } body { margin-bottom: 20px; } </style>
