Control-specific Handler (Magic xpa 3.x)

You can also condition handler execution by specifying that the handler only be executed when the corresponding event is triggered from a specific form control.

You can limit the handler to a specific control by selecting the control from the Controls list. You access the Controls list by zooming from the placeholder that is prefixed by On:. You may also define the control’s name by manually typing its name.

Note:

When there are several handlers for the same event in the same task, the runtime engine first searches the control-specific handlers and executes them if they match the control. Only after these handlers are executed does the engine scan for non-control-specific handlers in the same task, again from the bottom of the Task Editor upwards.

Accessing Control-specific Handlers from the Form Designer

You can easily create a new event handler for a specific control, view its already defined handler, and switch to these handlers directly from the visual representation of the control on the Form Designer.

In the context menu opened from a control, you can see the names of the already defined handlers. Selecting one of these menu options automatically switches to the handler’s logic unit definition in the logic layer.
