Master Detail (Vue)

The simplest way to deal with hierarchical data is the master-detail model. Use a control to select the main item and one or more additional controls to show the main item's details.

This example uses Vue.

<template> <div class="container-fluid"> <p> For example, the ComboBox below is used as a master control. Select a country from the combo and the grid below will show the items in that country: </p> <label>Select a country: <wj-combo-box :initialized="initCountriesCombo" :itemsSource="countries" :selectedIndexChanged="onCountriesSelectedIndexChanged" /> </label> <wj-flex-grid :itemsSource="detailView" /> <p> In the next example, The FlexGrid is used as the master control. Select an item on the grid and see the details in the controls below: </p> <h3>Master</h3> <wj-flex-grid :isReadOnly="true" :selectionMode="'Row'" :itemsSource="gridData" :initialized="initGridMaster" :selectionChanged="onSelectionChanged" /> <h3>Detail</h3> <table class="tbl-spaced"> <tr> <td>Country:</td> <td> <wj-combo-box id="theCountry" class="bnd-ctl" :itemsSource="countries" :textChanged="this.setProperty.bind(this,'country')" /> </td> </tr> <tr> <td>Product:</td> <td> <wj-combo-box id="theProduct" class="bnd-ctl" :itemsSource="products" :textChanged="this.setProperty.bind(this,'product')" /> </td> </tr> <tr> <td>Date:</td> <td> <wj-input-date id="theDate" class="bnd-ctl" :valueChanged="this.setProperty.bind(this,'date')" /> </td> </tr> <tr> <td>Sales:</td> <td> <wj-input-number id="theSales" class="bnd-ctl" :format="'n2'" :step="10" :valueChanged="this.setProperty.bind(this,'sales')" /> </td> </tr> <tr> <td>Expenses:</td> <td> <wj-input-number id="theExpenses" class="bnd-ctl" :format="'n2'" :step="10" :valueChanged="this.setProperty.bind(this,'expenses')" /> <td> </tr> </table> <p></p> </div> </template> <script> import "@grapecity/wijmo.styles/wijmo.css"; import "bootstrap.css"; import Vue from "vue"; import { CollectionView, Control, DateTime, isString } from "@grapecity/wijmo"; import "@grapecity/wijmo.vue2.input"; import "@grapecity/wijmo.vue2.grid"; let App = Vue.extend({ name: "app", data: function() { return { countries: "US,Germany,UK,Japan,Italy,Greece".split(","), products: "Phones,Cars,Stereos,Watches,Computers".split(","), gridData: null, detailView: null }; }, methods: { onCountriesSelectedIndexChanged: function() { if (this.detailView) { this.detailView.refresh(); } }, onSelectionChanged: function() { var item = this.theGridMaster.collectionView.currentItem; var bndCtls = document.querySelectorAll(".bnd-ctl"); for (var i = 0; i < bndCtls.length; i++) { var host = bndCtls[i]; var prop = host.id.substr(3).toLowerCase(); var ctl = Control.getControl(host); if (isString(item[prop])) { ctl["text"] = item[prop]; } else { ctl["value"] = item[prop]; } } }, setProperty: function(prop, sender) { var v = this.theGridMaster.collectionView; if (v) { var val = prop === "country" || prop === "product" ? sender.text : sender.value; v.editItem(v.currentItem); v.currentItem[prop] = val; v.commitEdit(); } }, getData: function() { var data = [], countries = this.countries, products = this.products; for (var i = 0; i < 50; i++) { data.push({ id: i, country: countries[Math.floor(Math.random() * countries.length)], product: products[Math.floor(Math.random() * products.length)], date: DateTime.addDays(new Date(), i), sales: Math.random() * 10000, expenses: Math.random() * 5000 }); } return data; }, initGridMaster: function(theGridMaster) { this.theGridMaster = theGridMaster; }, initCountriesCombo: function(countriesCombo) { this.countriesCombo = countriesCombo; } }, mounted: function() { // initalize top grid/detail this.gridData = this.getData(); var self = this; this.detailView = new CollectionView(this.gridData, { filter: function(item) { return item.country === self.countriesCombo.text; } }); // initialize bottom detail setTimeout(() => { this.onSelectionChanged(); }); } }); new Vue({ render: h => h(App) }).$mount("#app"); </script> <style> .wj-flexgrid { max-height: 220px; margin: 6px 0px; } .tbl-spaced td { vertical-align: middle; margin: 3px; } body { margin-bottom: 24pt; } </style>
