Footer aggregate in Vue Grid component

3 May 202415 minutes to read

The Syncfusion Vue Grid component allows you to calculate and display aggregate values in the footer cells. The footer aggregate value is calculated from all the rows in the grid. You can use the footerTemplate property to render the aggregate value in the footer cells.

app.vue
<template>
    <div id="app">
        <ejs-grid :dataSource='data' height='210px'>
            <e-columns>
                <e-column field='OrderID' headerText='Order ID' textAlign='right' width=120></e-column>
                <e-column field='CustomerID' headerText='Customer ID' width=150></e-column>
                <e-column field='Freight' width=150></e-column>
                <e-column field='ShipName' headerText='Ship Name' width=150></e-column>
            </e-columns>
            <e-aggregates>
                <e-aggregate>
                    <e-columns>
                        <e-column type="Sum" field="Freight" :footerTemplate='footerSum'></e-column>
                    </e-columns>
                </e-aggregate>
                <e-aggregate>
                    <e-columns>
                        <e-column type="Max" field="Freight" :footerTemplate='footerMax'></e-column>
                    </e-columns>
                </e-aggregate>
          </e-aggregates>
        </ejs-grid>
    </div>
</template>
<script>
import Vue from "vue";
import { GridPlugin, Aggregate } from "@syncfusion/ej2-vue-grids";
import { data } from './datasource.js';

Vue.use(GridPlugin);

export default {
  data() {
    return {
      data: data,
      footerSum: function () {
        return  { template : Vue.component('sumTemplate', {
            template: `<span>Sum: {{data.Sum}}</span>`,
            data () {return { data: {}};}
            })
          }
      },
      footerMax: function () {
        return  { template : Vue.component('maxTemplate', {
            template: `<span>Max: {{data.Max}}</span>`,
            data () {return { data: {}};}
            })
          }
      }
    };
  },
  provide: {
      grid: [Aggregate]
  }
}

Use the template reference variable name #footerTemplate to specify the footer template.

Inside the template, access the aggregate values using their corresponding type name. For example, to access the sum aggregate value, use data.sum.

Format the aggregate value

To format the aggregate value result in the Syncfusion Vue Grid component, you can use the format property of theAggregateColumnDirective. The format property allows you to specify a format string that determines how the aggregate value will be displayed.

app.vue
<template>
    <div id="app">
        <ejs-grid :dataSource='data' height='210px'>
            <e-columns>
                <e-column field='OrderID' headerText='Order ID' textAlign='right' width=120></e-column>
                <e-column field='CustomerID' headerText='Customer ID' width=150></e-column>
                <e-column field='Freight' width=150></e-column>
                <e-column field='ShipName' headerText='Ship Name' width=150></e-column>
            </e-columns>
            <e-aggregates>
                <e-aggregate>
                    <e-columns>
                        <e-column type="Sum" field="Freight" format="N0" :footerTemplate='footerSum'></e-column>
                    </e-columns>
                </e-aggregate>

How to place aggregates on top of the Grid

By default, the aggregated values are placed at the bottom of the footer section. It is possible to place the aggregated values at the top of the header. This is achieved by using the dataBound event, getHeaderContent, and getFooterContent methods of the Grid.

In the following, footer content is appended to the header content using the dataBound event of the Grid.

app.vue
<template>
    <div id="app">
        <ejs-grid ref='grid' :dataSource='data' height='210px' :dataBound='dataBound'>
            <e-columns>
                <e-column field='OrderID' headerText='Order ID' textAlign='right' width=120></e-column>
                <e-column field='CustomerID' headerText='Customer ID' width=150></e-column>
                <e-column field='Freight' headerText='Freight' format='C2' width=150></e-column>
                <e-column field='ShipName' headerText='Ship Name' width=150></e-column>
            </e-columns>
            <e-aggregates>
                <e-aggregate>
                    <e-columns>
                        <e-column type='Sum' field='Freight' format='C2' :footerTemplate='footerSum'></e-column>
                    </e-columns>
                </e-aggregate>
                <e-aggregate>
                    <e-columns>
                        <e-column type='Max' field='Freight' format='C2' :footerTemplate='footerMax'></e-column>
                    </e-columns>
                </e-aggregate>

          }
