EventHandler Function

Structure

The EventHandler pattern reads the input values from the Event Parameter Store (see also the PopulateWebInputVariable pattern).  The EventHandler is the basic pattern used when defining Event Handler functions in a Websydian application.

The EventHandler pattern scopes the IdentifyInputFields function called by Document Template Generator and the Page Generator functions using the Event Handler.

The WSYVAL patterns EventHandlerWithFieldConversion and EventHandlerWithValidation use this pattern to implement further functionality for Event handler functions.

More Information

The Event Handler functions belong to the Websydian main functions.  Read more about the Event Handler functions and how to implement them.
