TreeGrid (Vue)

Build powerful TreeGrids in JavaScript with FlexGrid. If your data items contain collections of child items, you may use FlexGrid's childItemsPath to show the data as a TreeGrid. For example, consider a list of 'person' objects which have a 'children' property. The 'children' property contains an array of more person objects. This is sometimes called a homogeneous hierarchy. The TreeGrid below was built by binding the grid to the top-level persons list and setting the childItemsPath property to 'children':

This example uses Vue.

<template> <div class="container-fluid"> <label> Show as Tree: <input type="checkbox" v-model="showAsTree" /> </label> <wj-flex-grid :items-source="family" headers-visibility="None" :child-items-path="showAsTree ? 'children' : ''"> <wj-flex-grid-column binding="name" header="Name" width="*" /> </wj-flex-grid> <p> There are also 'heterogeneous' hierarchies, where items at different levels have different types and different child item properties.</p> <p> For example, the grid below is bound to a collection of 'worker' objects which receive 'checks' which list 'earnings':</p> <wj-flex-grid :items-source="workers" headers-visibility="Column" :child-items-path="['checks', 'earnings']"> <wj-flex-grid-column binding="name" header="Name" /> <wj-flex-grid-column binding="hours" data-type="Number" :allow-sorting="false" /> <wj-flex-grid-column binding="rate" data-type="Number" :allow-sorting="false" /> </wj-flex-grid> </div> </template> <script> import "@mescius/wijmo.styles/wijmo.css"; import "bootstrap.css"; import { createApp } from "vue" import { registerGrid } from "@mescius/wijmo.vue2.grid"; import { getFamilies, getWorkers } from "./data"; let App = { name: "App", data: function () { return { showAsTree: true, family: getFamilies(), workers: getWorkers() } } }; const app = createApp(App); registerGrid(app) app.mount('#app'); </script> <style> .wj-flexgrid { max-height: 220px; margin: 6px 0; } .wj-cell.wj-group { border: none; } .wj-cell.wj-group:not(.wj-state-selected):not(.wj-state-multi-selected) { background-color: white; } body { margin-bottom: 24px; } </style>
