Create PDF Form Fields in Angular

2 Feb 202624 minutes to read

You can create or add new form fields either visually using the Form Designer UI or dynamically using APIs.

Create Form Fields Using the Form Designer UI

Use this approach when you want to design forms manually without writing code.

Steps:

1. Enable Form Designer mode in the PDF Viewer.
2. Click a form field type (Textbox, Checkbox, Dropdown, etc.) from the toolbar.
3. Click on the PDF page to place the form field.
4. Move or resize the field as required.
5. Configure field properties using the Properties panel.

Add Form Fields Programmatically (API)

Use this approach when you want to generate form fields dynamically based on data or application logic.

Standalone

import { Component, ViewChild } from '@angular/core';
import {
  ToolbarService,
  MagnificationService,
  NavigationService,
  AnnotationService,
  TextSelectionService,
  TextSearchService,
  FormFieldsService,
  FormDesignerService,
  PdfViewerModule,
  PdfViewerComponent,
} from '@syncfusion/ej2-angular-pdfviewer';

@Component({
  selector: 'app-root',
  standalone: true,
  imports: [PdfViewerModule],
  template: `
    <div class="content-wrapper">
      <ejs-pdfviewer #pdfViewer id="pdfViewer" (documentLoad)="onDocumentLoad()"
        [resourceUrl]="resourceUrl"
        [documentPath]="document"
        style="height: 640px; display: block;">
      </ejs-pdfviewer>
    </div>
  `,
  providers: [
    ToolbarService,
    MagnificationService,
    NavigationService,
    AnnotationService,
    TextSelectionService,
    TextSearchService,
    FormFieldsService,
    FormDesignerService,
  ],
})
export class AppComponent {
  public document: string = 'https://cdn.syncfusion.com/content/pdf/form-filling-document.pdf';
  public resourceUrl: string = 'https://cdn.syncfusion.com/ej2/31.1.23/dist/ej2-pdfviewer-lib';

  @ViewChild('pdfViewer') public pdfviewer!: PdfViewerComponent;

  onDocumentLoad(): void {
    this.pdfviewer.formDesignerModule.addFormField('Textbox', {
      name: 'First Name',
      bounds: { X: 146, Y: 229, Width: 150, Height: 24 },
      pageNumber: 1,
      isRequired: true,
      tooltip: 'Enter your first name'
    } as any);
  }
}

Use programmatic creation when:

• Building dynamic forms
• Pre-filling forms from databases
• Automating form creation workflows

Edit Form Fields in Angular PDF Viewer

You can edit form fields using the UI or API.

Edit Using the UI

• Drag to move; use handles to resize.
• Use the toolbar to toggle field mode or add new fields.
