Alpha Anywhere is constantly being enhanced, often times in response to questions/requests from actual users.

Here is an example of such a customer driven enhancement.

Using the Server-side AfterQuery Event - Computing a Column Total


For List controls that are based on a SQL query, the server-side AfterQuery event fires after the query to get the List data has been executed. This event is typically used to compute some Javascript code to return to the browser.

In this video we show how the event can be used to return the total for a column in the List. Since the List is paginated, all of the data in the List query is not currently shown in the List and therefore the calculation of the total must be done on the server.
