Customize Cell Appearance

For Angular, AngularJS, and Knockout apps, DevExtreme provides the dxTemplate markup component. The following code shows how to use dxTemplate to define templates for cells.

Angular
HTML
TypeScript
<dx-calendar
    [(value)]="currentDate">
    <span *dxTemplate="let cellData of 'cell'; let i = index"
         [style.font-style]="i == 0 || i == 6 ? 'italic' : 'normal'">
         {{cellData.text}}
    </span>
</dx-calendar>
import { DxCalendarModule } from "devextreme-angular";
// ...
export class AppComponent {
    currentDate: Date = new Date();
}
@NgModule({
    imports: [
        // ...
        DxCalendarModule
    ],
    // ...
})
Vue
App.vue
<template>
    <DxCalendar
        :value="date"
        cell-template="cell"
    >
        <template #cell="{ data: cell, index }">
            <span :style="{ fontStyle: index === 0 || index === 6 ? 'italic' : 'normal' }">
                {{ cell.text }}
            </span>
        </template>
    </DxCalendar>
</template>

<script>
import 'devextreme/dist/css/dx.common.css';
import 'devextreme/dist/css/dx.light.css';

import DxCalendar from 'devextreme-vue/calendar';

export default {
    components: {
        DxCalendar
    },
    data() {
        return {
            date: new Date()
        }
    }
}
</script>
React
App.js
import React from 'react';

import 'devextreme/dist/css/dx.common.css';
import 'devextreme/dist/css/dx.light.css';

import Calendar from 'devextreme-react/calendar';

const date = new Date();
function CustomCell(cellInfo, index) {
    return (
        <span style={{ fontStyle: index === 0 || index === 6 ? 'italic' : 'normal' }}>
            { cellInfo.text }
        </span>
    );
}

class App extends React.Component {
    render() {
        return (
            <Calendar
                defaultValue={date}
                cellRender={CustomCell} />
        );
    }
}
export default App;

If you use jQuery alone, use DOM manipulation methods to combine the HTML markup for cells. To apply this markup, use the cellTemplate callback function as shown in the following code.

JavaScript
$(function () {
    $("#calendarContainer").dxCalendar({
        value: new Date(),
        cellTemplate: function (cellData, cellIndex, cellElement) {
            var italic = $("<span>").css('font-style', 'italic')
                                    .text(cellData.text);
            var normal = $("<span>").text(cellData.text);
            return (cellIndex == 0 || cellIndex == 6) ? italic : normal;
        }
    });
});

In addition, you can use a 3rd-party template engine to customize widget appearance. For more information, see the 3rd-Party Template Engines article.
