Password

The Password control is a type of Input control that is used to display and input masked data or text. Asterisks are used to display all characters displayed or entered in the Password control. You can use the getValue() method of the HTML element to view the actual text in the Password control. Unless the field displays password information from the database, the Password control is used as a free-form control.

Password controls can be data-bound or free-form controls. When data-bound, a Password control is bound to a model from which it fetches data. When you change the data in the control, the model is updated and all controls associated with the model are refreshed. You can use a free-form Password control to display and accept any arbitrary text.

You can bind a Password control to a model by setting the Reference property of the associated business object in the control's property sheet. To do so, specify the XPath of the business object's data to be bound. If no model is set for the control, then the control is bound to the model of its parent control, by default.

Properties, Events, and Methods of the Control

The properties, events, and methods associated with the Password control define its behavior. You can set them through the control's property sheet during design time.

Table 1. List of Properties

Design-time property	Runtime property	Description
ID		Sets the string that identifies the control on an XForm. If not specified, a unique ID is automatically generated.
Tab Index		Sets and retrieves the position of the current control in the tabbing order for the current XForm.
Model		Sets the ID of the data model from which the data (specified using the Reference property) is displayed in the control. If model is not specified, it is inherited from the parent control's model.
Reference (xql)		Sets the location or expression for the XPath that contains the data (value) displayed in the control. The XPath refers to the child node or descendants of the immediate parent control's reference.
Class Name	className	Sets or retrieves the class name applied on the control.
Tooltip	title	Sets the tool tip that appears on a control when the mouse is moved over it. Programmatically, this property is set by specifying the title property of the control.
Constraint Validation On Change		Denotes whether validation constraints need to be applied to validate data according to the business logic, when the data associated with a control is changed. This property is available only when a WS-AppServer model is set for a control.
	businessObject	Retrieves the root node of the XML data associated with the control; the location of the data is specified by the Reference property.
	currentContext	Retrieves the immediate parent of the data that the control represents. This data is the child node of the business object.
	data	Retrieves the XML node of the data (value) that the control represents. The location (XPath) of this XML inside the business object is set through the Reference property.

Table 2. List of Events

Event	Description
Change	This event is activated on modifying data in the control, after the Validate event has been fired.
Data Bind	This event is activated before the data is bound to the control.
InFocus	This event is activated when you highlight or focus upon the control.
OutFocus	This event is activated when the control loses its focus.
Validate	This event is activated after the value of the control is changed and the new value is successfully validated against the settings specified in the Formating Options dialog box.

Table 3. List of Methods

Method	Description
addListener()	This method registers the control to receive notifications for an event.
create()	This method is available for data-bound controls only. It creates an instance of the business object for the control.
disable()	This method disables the control on which it is invoked.
enable()	This method enables the control on which it is invoked.
getBusinessObject()	This method retrieves data or business object.
getEBIValidate()	This method retrieves the value that indicates whether a validate request was sent to the Cordys WS-AppServer when the data in the control was changed.
getFormattedValue()	This method returns the value that is to be displayed in the control.
getLabel()	This method returns the label object associated with the control. It is available for all controls associated with labels.
getValue()	This method returns the original value of the control, as available in the database.
hide()	This method hides controls and all associated child controls.
isEnabled()	This method retrieves the value that denotes whether the control is enabled or not.
rebind(oBusinessObject)	This method is available for all controls bound to a model. This method refreshes the control with data from the business object that is passed as a parameter. If no parameter is passed, the business object of the model's activeTuple node is used and the control is refreshed.
remove()	This method is available only for data-bound controls. It removes the instances marked for deletion.
removeListener()	This method unregisters the control to cease receiving notifications for its events.
setEBIValidate()	This method sets the value that indicates whether a validate request must be sent to the Cordys WS-AppServer when the data in the control changes.
setLabel(sText)	This method sets the text that is passed as a parameter to the label object associated with the control. It is available for all controls associated with a label.
setValue(sValue)	This method sets the value of the control. The sValue parameter denotes the value to be set for the control.
show()	This method makes the control and its child controls visible.
