The ASP.NET Core Word Processor component supports legacy form fields like text, checkboxes, and dropdown lists to create fillable forms in a Word document. These form fields are supported in both DOC and DOCX formats.

Create a fillable form

The ASP.NET Core Word Processor component has an intuitive UI for designing a fillable form in a Word document by inserting legacy form fields. The legacy form fields allow you to design:

  • Text form fields with text type to fill any string value.
  • Text form fields with number type to fill a numeric value.
  • Text form fields with date type to fill a date or time.
  • Checkbox form fields to answer a simple yes-or-no question.
  • Dropdown form fields to choose one value from a list of strings.


On clicking or navigating to a text form field, this mode opens a pop-up that features an in-place editor for filling form fields seamlessly within the document. By default, this mode is enabled to streamline the form-filling process.

This mode grants users the ability to fill text form fields directly within the document interface, eliminating the need for any pop-ups. Users can enter information directly into the form fields without interruption, enhancing the efficiency and convenience of the form-filling experience.
