Local data in Vue Grid component
28 Mar 20235 minutes to read
To bind local data to the grid, you can assign a JavaScript object array to the dataSource
property. The local data source can also be provided as an instance of the DataManager
.
<template>
<div id="app">
<ejs-grid :dataSource="data" height='315px' >
<e-columns>
<e-column field='OrderID' headerText='Order ID' textAlign='Right' width=90></e-column>
<e-column field='CustomerID' headerText='Customer ID' width=120></e-column>
<e-column field='Freight' headerText='Freight' textAlign='Right' format='C2' width=90></e-column>
<e-column field='OrderDate' headerText='Order Date' textAlign='Right' format='yMd' type='date' width=120></e-column>
</e-columns>
</ejs-grid>
</div>
</template>
<script>
import Vue from "vue";
import { GridPlugin } from "@syncfusion/ej2-vue-grids";
import { data } from './datasource.js';
Vue.use(GridPlugin);
export default {
data() {
return {
data: data
};
}
}
</script>
<style>
@import "../node_modules/@syncfusion/ej2-vue-grids/styles/material.css";
</style>
By default,
DataManager
usesJsonAdaptor
for local data-binding.
Refresh the data source
You can add/delete the datasource records through an external button. To reflect the datasource changes in grid, you need to invoke the refresh
method.
Please follow the below steps to refresh the grid after datasource change.
Step 1: Add/delete the datasource record by using the following code.
this.data.unshift(customData); // Add a new record.
this.data.splice(selectedRow, 1); // Delete a record.
Step 2: When applied the changes in dataSource then refresh Grid at own.
this.data = [...this.data]; // Refresh the Grid dataSource.
