Render model dialog with Rich Text Editor

4 Apr 20222 minutes to read

This section explains how to render model dialog with the Rich Text Editor component. When you render model dialog with the Rich Text Editor component, the first row of the content will be hidden because the dialog container and its wrapper elements are styled with display as none. So, the editor’s toolbar does not get proper offset width and rendered above the edit area container. In this scenario, use the refreshUI method on the Dialog open event.

<div id='container' style="height:400px;">
    <ejs-button id="targetButton" content="Open Modal Dialog"></ejs-button>
    <ejs-dialog id='dialog' isModal="true" width="300px" overlayClick="onOverlayClick" open="dlgopen" target="#container">
            <ejs-richtexteditor id="defaultRTE">


    window.onload = function () {
        document.getElementById('targetButton').onclick = function () {
            var dialog = document.getElementById("dialog").ej2_instances[0];
    function onOverlayClick() {
        var dialog = document.getElementById("dialog").ej2_instances[0];
    function dlgopen() {
        var RTE = document.getElementById("defaultRTE").ej2_instances[0];
public class HomeController : Controller
    public ActionResult Index()
        return View();
