Remarks
When you export a document to PDF, enable the ExportEditingFieldsToAcroForms property to generate a fillable PDF form (AcroForms). The fields that you make editable in Print Preview remain fillable in the resulting PDF document.
Limitations
The following limitations apply when you export editable fields to PDF AcroForms:
Text Fields
PDF AcroForms do not support field content’s vertical alignment.
Single-line field text becomes center-aligned. Multi-line text is top-aligned.
Text is multi-line if it contains new line characters or if word wrap is specified in the field’s format string.
Character Comb Fields
The XRCharacterComb control’s interactive content cannot be multi-line in the resulting PDF file.
When this control displays text on multiple lines, it is converted to individual lines in PDF export.
Check Boxes
A radio group is maintained in a PDF file only if it is contained on one page.
To make a radio group read-only, enable the radio group’s first control’s ReadOnly property. An individual check box cannot be read-only within a radio group.
Image Fields
PDF image fields do not support the Tile size mode. Image controls that are set to this mode are exported to PDF in the Normal mode.
Drop-Down Lists
Print Preview supports custom drop-down lists but these fields are not exported to PDF.
Editable fields are not exported to PDF in the PDF/A-1b compatibility mode.
When you export editable text fields to PDF, fonts that are used to populate these fields are selected according to PDF export settings. However, non-embedded fonts are always used to populate these fields in a PDF viewer.
AcroForms Field Names
Form field names are generated in the following way:
For regular fields, the name pattern is EditingField.ID_#. It consists of three parts: the EditingField.ID property value, an underscore sign, and an automatically incremented zero-based counter. If the EditingField.ID value is not provided, the “AcroFormField“ literal is used instead.
For instance, AcroFormField_0 (if EditingField.ID is empty) or label1_3 (if EditingField.ID is set to label1).
- For group fields, the name pattern is RadioGroupAcroFormField_groupName, where RadioGroupAcroFormField is a hard-coded literal and groupName is the CheckEditingField.GroupID property value. For instance, RadioGroupAcroFormField_myGroup.
- Multi-line Character Comb editors are split into distinct editors that follow the same name conversion.
