Template in Angular Dialog component

17 Nov 20227 minutes to read

In Dialog the template support is provided to the header, content and footer sections. So any text or HTML content can be appending in these sections.

The Dialog header content can be provided through the header property, and it will allow both text and any HTML content as a string.
Also in header, close button is provided as built-in support, and this can be enabled through the showCloseIcon property.

The Dialog footer can be enabled by adding built-in buttons or providing any HTML string through the footerTemplate.

The buttons and footerTemplate properties can’t be used at the same time.


The Dialog content can be update by providing any HTML string through the content.

The below example demonstrates the usage of header, footer and content as template in the Dialog.

import { Component, ViewChild, OnInit, ElementRef } from '@angular/core';
import { DialogComponent } from '@syncfusion/ej2-angular-popups';
import { EmitType, isNullOrUndefined } from '@syncfusion/ej2-base';

    selector: 'app-root',
    template: `
    <button class="e-control e-btn" style="position: absolute;" id="targetButton" (click)="onOpenDialog($event)">Open Dialog</button>
      <div #container class='root-container'></div>
      <ejs-dialog id='dialog' #template showCloseIcon='true' (open)="dialogOpen()" [height]='height' [target]='targetElement' width='435px'>
      <ng-template #footerTemplate>
            <input id="inVal" class="e-input" type="text" placeholder="Enter your message here!"/>
            <button id="sendButton" class="e-control e-btn e-primary sendButton" data-ripple="true">Send</button>
        <ng-template #content>
            <div class="dialogContent">
                <span class="dialogText">Greetings Nancy! When will you share me the source files of the project?</span>
        <ng-template #header>
            <img class="img2" src="https://ej2.syncfusion.com/products/typescript/dialog/template/images/1.png" style="display: inline-block;" alt="header image"/>
            <div title="Nancy" class="e-icon-settings dlg-template"> Nancy </div>

        (document.getElementById('sendButton') as any).keypress = (e: any) => {
            if (e.keyCode === 13) { this.updateTextValue(); }
        (document.getElementById('inVal')as HTMLElement).onkeydown = (e: any) => {

            dialogTextElement.innerHTML = enteredVal.value;
        enteredVal.value = '';
