Image Gallery Component Events

Server-side Events

All server-side events have access to the following properties, available via the e object, which is passed to both events.

e.tmpl

An object containing the Image Gallery component's definition (i.e. properties.) You can modify the definition to change the Image Gallery component's behavior.

e.rtc

An object for storing runtime calculations. Placing data in e.rtc makes it available to Xbasic in other server-side events.

e.arguments

SQL::Arguments object that contains the values assigned to arguments defined in the Image Gallery component. Arguments can be read using the find() method. For example: e.arguments.find("argumentName").data

Server-side events can also access Server objects to create or read session, request, and response variables. See the Context Object to learn more about methods available for these objects.

Request

The Request object. See Request Object for methods available for the Request object on the Classic Application Server. IMPORTANT If you are running the Application Server for IIS, you must use Context.Request, not Request to access the request variable information. See Context.Request object for more information.

Session
