Protect the document in comments only mode

Document Editor provides support for protecting the document with CommentsOnly protection. In this protection, user allowed to add or edit comments alone in the document.

Document editor provides an option to protect and unprotect document using enforceProtection and stopProtection API.

The following example code illustrates how to enforce and stop protection in Document editor container.

import { Component, ViewEncapsulation, ViewChild } from '@angular/core';
import { DocumentEditorContainerComponent, ToolbarService } from '@syncfusion/ej2-angular-documenteditor';

@Component({
      selector: 'app-container',
      // specifies the template string for the Document Editor component
      template: `<div><button ejs-button (click)="protectDocument()" >Protect</button>
      <button ejs-button (click)="unProtectDocument()" >Unprotect</button>
      <ejs-documenteditorcontainer #document_editor serviceUrl="https://ej2services.syncfusion.com/production/web-services/api/documenteditor/" height="600px" style="display:block" [enableToolbar]=true> </ejs-documenteditorcontainer></div>`,
      encapsulation: ViewEncapsulation.None,
      providers: [ToolbarService]
})
export class AppComponent {
    @ViewChild('document_editor')
    public container: DocumentEditorContainerComponent;

    public protectDocument(): void {
        //enforce protection
        container.documentEditor.editor.enforceProtection('123', 'CommentsOnly');
    }

    public unProtectDocument(): void {
        //stop the document protection
        container.documentEditor.editor.stopProtection('123');
    }
}

Comment only protection can be enabled in UI by using Restrict Editing pane

Note: In enforce Protection method, first parameter denotes password and second parameter denotes protection type. Possible values of protection type are NoProtection |ReadOnly |FormFieldsOnly |CommentsOnly. In stop protection method, parameter denotes the password.

Mention support in Comments

Mention support displays a list of items that users can select or tag from the suggested list. To use this feature, type the @ character in the comment box and select or tag the user from the suggestion list.

The following example illustrates how to enable mention support in the Document Editor

import { Component, OnInit } from '@angular/core';
import { ToolbarService , DocumentEditorSettingsModel } from '@syncfusion/ej2-angular-documenteditor';
@Component({
      selector: 'app-root',
      // specifies the template string for the DocumentEditorContainer component
      template: `<ejs-documenteditorcontainer serviceUrl="https://ej2services.syncfusion.com/production/web-services/api/documenteditor/" height="600px" style="display:block" [documentEditorSettings]= "settings" [enableToolbar]=true> </ejs-documenteditorcontainer>`,
      providers: [ToolbarService]
})
