Field Detail

NORMAL

public static final FormControlOutputStyle NORMAL
Normal display of the output element.

This is the default display style.


REMOVE

public static final FormControlOutputStyle REMOVE
Remove the output element from the output document completely.


DISPLAY_VALUE

public static final FormControlOutputStyle DISPLAY_VALUE
The normal output element is replaced with a simple representation of the form control's submission value(s).

The implementation of this functionality is highly subjective, but provides a more aesthetic way of displaying a read-only version of a form without having to resort to using disabled controls.

The representation is dependent on the form control type, and can be configured using the static properties of the ConfigDisplayValue nested class.

Unless specified otherwise below, the normal output element is replaced with a display value element having the name specified in the static ConfigDisplayValue.ElementName property (div by default). The attributes specified in the static ConfigDisplayValue.AttributeNames list (id, class and style by default) are copied from the normal output element into the display value element.

Details of the content of the display value element or other representation of the control value are as follows:

TEXT, FILE
The content of the display value element is the re-encoded value of the normal output element's value attribute.
TEXTAREA
The content of the display value element is the content of the TEXTAREA element re-encoded with white space formatting.
CHECKBOX, RADIO
The normal output element is replaced with the un-encoded content specified in the ConfigDisplayValue.CheckedHTML or ConfigDisplayValue.UncheckedHTML static property, depending on whether the normal output element contains a checked attribute. If the relevant static property has a value of null (the default), the output element is simply a disabled version of the form control. Attempting to determine which labels might apply to which checkbox or radio button, allowing only the selected controls to be displayed, would require a very complex and inexact algorithm, so is best left to the developer to implement if required.
SELECT_SINGLE, SELECT_MULTIPLE
The content of the display value element is the re-encoded label of the currently selected option. In the case of a SELECT_MULTIPLE control, all labels of selected options are listed, separated by the text specified in the static ConfigDisplayValue.MultipleValueSeparator property (", " by default).
PASSWORD
The content of the display value element is the encoded character specified in the ConfigDisplayValue.PasswordChar static property ('*' by default), repeated n times, where n is the number of characters in the control's submission value.
HIDDEN
The output element is removed completely.
BUTTON, SUBMIT, IMAGE
The output element is a disabled version of the original form control.

If the submission value of the control is null or an empty string, the display value element is given the un-encoded content specified in the ConfigDisplayValue.EmptyHTML static property.
