Working with Form Fields
Form Fields Overview
A document that contains fill-in blanks (fields) is known as a form. For example, you can create a registration form in Microsoft Word that uses drop-down lists from which users can select entries. The Form field is a location where a particular type of data, such as a name or address, is stored. Form fields in Microsoft Word include text input, combobox and checkbox.
You can use form fields in your project to “communicate” with your users. For example, you create a document whose content is protected, but only form fields are editable. The users can enter the data in the form fields and submit the document. Your application that uses Aspose.Words can retrieve data from the form fields and process it.
