The report designer supports events that provide the ability to perform necessary operations before specific actions-both on the JavaScript client side and the Python server side. A detailed description of how events work can be found in the Report Engine Events section.

Some event arguments take values from enumerations that are located in specific namespaces. All the enumerations used in designer events are listed in the code block below:

 

app.py

 

from stimulsoft_reports.enums import StiEventType

 

 

 

The designer supports the following events:

•onPrepareVariables
•onBeginProcessData
•onEndProcessData
•onCreateReport
•onOpenReport
•onOpenedReport
•onSaveReport
•onSaveAsReport
•onPreviewReport
•onExit
