Integrating Rich Text Editor in Dialog Components

16 Jan 20253 minutes to read

When rendering the Rich Text Editor inside a Dialog component, the dialog container and its wrapper elements are initially styled with display: none. This styling prevents the editor’s toolbar from calculating the proper offset width. As a result, the toolbar may render incorrectly, appearing above the edit area container.

To resolve this issue, we can utilize the refreshUI method of the Rich Text Editor in conjunction with the open event. This approach ensures that the Rich Text Editor’s UI is properly refreshed and rendered once the Dialog is visible.

import { Component, ViewChild } from '@angular/core';
import { DialogComponent, DialogModule } from '@syncfusion/ej2-angular-popups';
import { RichTextEditorComponent, RichTextEditorModule, ToolbarSettingsModel, ToolbarService, LinkService, ImageService, HtmlEditorService, QuickToolbarService, TableService, PasteCleanupService } from '@syncfusion/ej2-angular-richtexteditor';
import { ButtonModule } from '@syncfusion/ej2-angular-buttons';

@Component({
  imports: [RichTextEditorModule, DialogModule, ButtonModule],
  standalone: true,
  selector: 'app-root',
  template: `
    <button ejs-button (click)="openDialog()">Open Dialog</button>
    <ejs-dialog #dialog [width]="'350px'" [height]="'400px'" [showCloseIcon]="true" [visible] ="false" (open)="onDialogOpen()">
      <ng-template #header>
        <div>Dialog Header</div>
      </ng-template>
      <ng-template #content >
        <ejs-richtexteditor #editor [toolbarSettings]='tools'></ejs-richtexteditor>
      </ng-template>
      <ng-template #footer>
      <div>Dialog Footer</div>
      </ng-template>
    </ejs-dialog>
  `,
  providers: [ToolbarService, LinkService, ImageService, HtmlEditorService, QuickToolbarService, TableService, PasteCleanupService]
})
export class AppComponent {
  @ViewChild('dialog') dialogObj!: DialogComponent;
  @ViewChild('editor') editorObj!: RichTextEditorComponent;

  public tools: ToolbarSettingsModel = {
    items: ['Bold', 'Italic', 'Underline', 'StrikeThrough',
      'FontName', 'FontSize', 'FontColor', 'BackgroundColor',
      'LowerCase', 'UpperCase', '|',
      'Formats', 'Alignments', 'OrderedList', 'UnorderedList',
      'Outdent', 'Indent', '|',
      'CreateLink', 'Image', '|', 'ClearFormat', 'Print',
      'SourceCode', 'FullScreen', '|', 'Undo', 'Redo']
  };

  public openDialog(): void {
    this.dialogObj.show();
  }

  public onDialogOpen(): void {
    this.editorObj.refreshUI();
  }
}
import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));
