To get or set property values for client API properties, you must call property accessor methods that are named with the get_ and set_ prefixes. For example, to get or set a value for a property such as cancel, you call the get_cancel or set_cancel methods. |
var arr = eventArgs.get_panelsCreated();
If an UpdatePanel control is updated as a result of a partial-page update, the array referenced in the panelsCreated property of the PageLoadedEventArgs class contains a reference to the corresponding div element. The pageLoaded event of the Sys.WebForms.PageRequestManager class uses a PageLoadedEventArgs object to return its event data.
