PdfRadioButtonField Class
Represents a radio button field in a set of related buttons that can each be on or off. Typically, at most one radio button in a set may be on at any given time, and selecting any one of the buttons automatically deselects all the others. (There are exceptions to this rule, as noted in "Radio Buttons").

| AnnotationType | Gets the Widget value. (Inherited from PdfField) |
| Appearance | Gets the appearance settings for this PdfToggleButtonField. (Inherited from PdfToggleButtonField) |
| AssociatedFiles | (Optional; PDF 2.0) An array of one or more PdfFileSpecifications which denote the associated files for this PdfAnnotation. (Inherited from PdfAnnotation) |
| Bounds | (Required) The annotation bounds, defining the location and the size of the annotation on the page in default user space units. (Inherited from PdfAnnotation) |
| Checked | Gets or sets a value indicating whether this PdfToggleButtonField is checked. (Inherited from PdfToggleButtonField) |
| DefaultValue | (Optional; inheritable) The default value to which the field reverts when a reset-form action is executed. The format of this value is the same as that of Value. (Inherited from PdfField) |
| Hidden | (PDF 1.2) If set, do not display the annotation on the screen or allow it to interact with the user. The annotation may be printed (depending on the setting of the Print flag) but should be considered hidden for purposes of on-screen display and user interaction. (Inherited from PdfField) |
| Locked | (PDF 1.4) If set, do not allow the annotation to be deleted or its properties (including position and size) to be modified by the user. However, this flag does not restrict changes to the annotation's contents, such as the value of a form field. (Inherited from PdfAnnotation) |
| Metadata | (Optional; PDF 1.4) A metadata stream containing metadata for the component. (Inherited from PdfObject) |
| Name | Gets the (fully qualified) field name. (Inherited from PdfField) |
| Page | Gets the page with which this annotation is associated. (Inherited from PdfAnnotation) |
(PDF 1.2) If set, print the annotation when the page is printed. If clear, never print the annotation, regardless of whether it is displayed on the screen. noteThis can be useful for annotations representing interactive pushbuttons, which would serve no meaningful purpose on the printed page. (Inherited from PdfField) | |
| ReadOnly | If set, the user may not change the value of the field. Any associated widget annotations will not interact with the user; that is, they will not respond to mouse clicks or change their appearance in response to mouse motions. This flag is useful for fields whose values are computed or imported from a database. (Inherited from PdfField) |
| Required | If set, the field shall have a value at the time it is exported by a submit-form action (see 12.7.5.2, "Submit-Form Action"). (Inherited from PdfToggleButtonField) |
| Tooltip | (Optional; PDF 1.3) An alternate field name that shall be used in place of the actual field name wherever the field shall be identified in the user interface (such as in error or status messages referring to the field). This text is also useful when extracting the document's contents in support of accessibility to users with disabilities or for other purposes (see 14.9.3, "Alternate Descriptions"). (Inherited from PdfField) |
| Value | Gets or sets the PdfToggleButtonField value as an instance of the System.String type. (Inherited from PdfToggleButtonField) |
