WidgetEventHandler

Namespace: Wisej.Web.Ext.Ignite

Assembly: Wisej.Web.Ext.Ignite (4.1.0.0)

Represents a JavaScript handler attached to an event fired by the third party widget.

public class WidgetEventHandler

The handler runs in the browser. It receives the event object in the e argument; any additional argument passed by the third party widget, i.e. the ui object of the Ignite UI events, is available in arguments.

Use e.container to refer to the wisej.web.Widget instance, and e.container.widget to refer to the third party widget. Call e.container.fireWidgetEvent(name, data) to fire the WidgetEvent event on the server.

This class is not related to the WidgetEventHandler delegate, which is used to handle widget events on the server.
