WinDDA events

Aplica-se a: Unified Service Desk 2.0

The Windows data-driven adapter (DDA) distinguishes between two types of events, application events and control events. This topic describes these two events.

Control events

Control events are fired by controls in an application. For all of these events, the control name must be specified during registration (RegisterActionForEvent). The controls must also be accessible in the application during registration. You can use the FindControl method or add an exception handler to ensure that the control is accessible.

The Toolkit de Aplicações Alojadas (HAT) Software Factory lists the events that are supported for a specific User Interface (UI) control type. If you do not specify the type in the UII Inspector, UII lists all events for the control. All available control events are listed by the Toolkit de Aplicações Alojadas (HAT) Software Factory if no control type is detected. The following table describes the supported control events.

 

Element Description

GotFocus

The event is raised when the control gets the focus.

LostFocus

The event is raised when the control loses the focus.

ButtonPressed

The event is raised when the button is clicked.

ButtonReleased

The event is raised when the button is released.

CheckBoxSet

The event is raised when the check box is selected.

CheckBoxCleared

The event is raised when the check box is cleared.

RadioButtonSet

The event is raised when the radio button is selected.

The following table lists the events that each control supports.

Application events

Application events are not bound to a control; therefore, you do not have to specify a control name in the RegisterActionForEvent activity. The following table describes the application events that are available in the Toolkit de Aplicações Alojadas (HAT):

 

Element Description

WindowShown

The event is raised when the window is displayed.

WindowDisappeared
