Interactive Form Filling

This document describes how to fill a document with interactive forms.

You are able to type directly into PDF documents that contain the form field information.

As you can see from the image above, each field is rendered according to its form type, providing text boxes, radio buttons and combo boxes with auto complete, check boxes and lists.

The image below shows the auto complete, combo box and check box features embedded in an address form.

The PDF Viewer can highlight interactive form fields with a color. To enable this functionality, set the PdfViewerControl.HighlightFormFields property to true.

After a form field value is changed, the PdfViewerControl.FormFieldValueChanged event is raised. The FormFieldValueChangedEventArgs.FieldName, FormFieldValueChangedEventArgs.OldValue and FormFieldValueChangedEventArgs.NewValue properties allow you to obtain the field name, the field's previous value and new value.

To specify a new value of the form field, use the FormFieldValueChangingEventArgs.NewValue property when the PdfViewerControl.FormFieldValueChanging event is handled.
