Web Dynpro AbstractInputField API -
IWDAbstractInputField 
Definition
The AbstractInputField class which implements the IWDAbstractInputField interface, is the abstract base class of input fields. The input field can be used to edit or display a single-line text. If you only want to display the text, set the property readOnly to true. You cannot only edit the value of the type String but also the value of a simple data type using an input field. The conversion of the string representation into the data type – known as parsing – and the conversion of the data type into the string presentation – known as formating – are automatically executed.
Description of the UI Element Properties
·
length
Determines the maximum number of characters to be
displayed in the input field.
·
passwordField
Boolean value that controls the display of entered
characters on screen. If the value is true, the entered characters on screen
are echoed with an asterisk (*). This attribute is usually used for password
input fields.
·
readOnly
Specifies whether the input
field can be edited or only read. If the value is true, the displayed text can only be
read.
·
state
Describes the status of the
UI element. The data type of this property corresponds to the enumeration type
WDState. You can use the following values in the
application:
Describes the default state of the UI element. |
|
Specifies whether the entered value is required. |
·
value
Specifies the character string displayed in the
input field area. This property must be bound to a context attribute (see 
Data Binding
Within Web Dynpro).
