This property is used to access or change the flags (Ff entry) for the field.

The FieldFlags type is a flags type enumeration so the different values can be combined together using bitwise operations. It may take the following values:

• ReadOnly (Do not let the user change the value of the field)
• Required (Require that the field has a value at the time it is exported by a form submission action)
• NoExport (Do not export the value of the field as part of a form submission action)
• NoToggleToOff (This is used for radio buttons and specifies that exactly one button shall be selected at all times)
• Radio (Indicates whether the field is a radio button or a checkbox. This field is ignored if the Pushbutton flag is set)
• Pushbutton (Whether this field is a pushbutton that stores no permanent value)
• RadiosInUnison (Allow radio buttons with the same 'on' value to turn on and off together)
• Multiline (Allow a text field to contain multiple lines of text)
• Password (Display text field as a password box in which the text contents are obscured)
• FileSelect (Display a text field that allows a file to be selected. When the form is submitted the contents of the file will be used as the value of the field)
• DoNotSpellCheck (Text in this text or choice field shall not be spell checked)
• DoNotScroll (Text in this text field shall not scroll. Once text has been entered which fills the field it shall accept no further characters)
• Comb (Use the MaxLen property to equally space out text field characters into a comb-like slot position)
• RichText (The value of this text field shall be a rich text string)
• Combo (Whether this field is a combo or list field)
• Edit (Whether field shall present an editable text box in addition to a list)
• Sort (Whether entries in the list shall be put into alphabetical order)
• MultiSelect (Whether more than one entry in the list can be selected at the same time)
• CommitOnSelChange (A change to the value of this field will be committed as soon as it is made)
