Disable header and footer edit in Angular Document editor component

28 Mar 20257 minutes to read

You can use restrictEditing property to disable header and footer editing based on selection context type.

RestrictEditing allows you to restrict the document modification and makes the Document read only mode. So, by using this property, and if selection inside header or footer, you can set this property as true.

The following example code illustrates how to header and footer edit in DocumentEditorContainer instance.

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

import { DocumentEditorContainerModule } from '@syncfusion/ej2-angular-documenteditor';

@Component({
  selector: 'app-container',
  standalone: true,
  imports: [DocumentEditorContainerModule],
  providers: [ToolbarService],
  template: `
    <ejs-documenteditorcontainer #documenteditor_default 
      serviceUrl="https://services.syncfusion.com/angular/production/api/documenteditor/" 
      height="600px" 
      style="display:block" 
      [enableToolbar]=true 
      (selectionChange)="selectionChanges()"
      >
    </ejs-documenteditorcontainer>
  `,
})
export class AppComponent implements OnInit {
  @ViewChild('documenteditor_default')
  public container?: DocumentEditorContainerComponent;
  ngOnInit(): void {}
  selectionChanges() {
    // Check whether selection is in header
    if (
      (
        this.container as DocumentEditorContainerComponent
      ).documentEditor.selection.contextType.indexOf('Header') > -1 ||
      // Check whether selection is in Footer
      (
        this.container as DocumentEditorContainerComponent
      ).documentEditor.selection.contextType.indexOf('Footer') > -1
    ) {
      // Change the document to read only mode
      (
        this.container as DocumentEditorContainerComponent
      ).restrictEditing = true;
    } else {
      // Change the document to editable mode
      (
        this.container as DocumentEditorContainerComponent
      ).restrictEditing = false;
    }
  }
}

Otherwise, you can disable clicking inside Header or Footer by using closeHeaderFooter API in selection module.

The following example code illustrates how to close header and footer when selection is inside header or footer in DocumentEditorContainer instance.

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

import { DocumentEditorContainerModule } from '@syncfusion/ej2-angular-documenteditor';

@Component({
  selector: 'app-container',
  standalone: true,
  imports: [DocumentEditorContainerModule],
  providers: [ToolbarService],
  template: `
    <ejs-documenteditorcontainer #documenteditor_default 
      serviceUrl="https://services.syncfusion.com/angular/production/api/documenteditor/" 
      height="600px" 
      style="display:block" 
      [enableToolbar]=true 
      (selectionChange)="selectionChanges()"
      >
    </ejs-documenteditorcontainer>
  `,
})
export class AppComponent implements OnInit {
  @ViewChild('documenteditor_default')
  public container?: DocumentEditorContainerComponent;
  ngOnInit(): void {}
  selectionChanges() {
    // Check whether selection is in header
    if (
      (
        this.container as DocumentEditorContainerComponent
      ).documentEditor.selection.contextType.indexOf('Header') > -1 ||
      // Check whether selection is in Footer
      (
        this.container as DocumentEditorContainerComponent
      ).documentEditor.selection.contextType.indexOf('Footer') > -1
    ) {
      // Close header Footer
      this.container?.documentEditor.selection.closeHeaderFooter();
    }
  }
}

Like restrictEditing, you can use isReadOnly property in Document editor to disable header and footer edit.

The following example code illustrates how to header and footer edit in DocumentEditor instance.

// import { Component, OnInit, ViewChild } from '@angular/core';
// import {
//   ToolbarService,
//   DocumentEditorContainerComponent,
// } from '@syncfusion/ej2-angular-documenteditor';
// @Component({
//   selector: 'app-root',
//   // specifies the template string for the DocumentEditorContainer component
//   template: `<ejs-documenteditorcontainer #documenteditor_default serviceUrl="https://services.syncfusion.com/angular/production/api/documenteditor/" height="600px" style="display:block" [enableToolbar]=false (selectionChange)="selectionChanges()"> </ejs-documenteditorcontainer>`
// })
// export class AppComponent implements OnInit {
//   @ViewChild('documenteditor_default')
//   public container: DocumentEditorContainerComponent;
//   ngOnInit(): void {}
// }
