Handling Events

DHTMLX Connector uses events to manage Insert/Update/Delete operations.

The code snippet below shows how to attach the beforeUpdate event:

class CustomBehavior extends ConnectorBehavior{
        @Override 
    public void beforeUpdate(DataAction data) {
        //any custom code
    } 
}
component.event.attach(new CustomBehavior());

Handler functions get one input parameter and this parameter depends on the attached event.

In the following table you'll see a full list of events and the appropriate input parameters of handler functions.

Event	Input parameter of handler function
beforeSort	SortInterface Object
beforeFilter	FilterInterface Object
beforeRender	DataItem Object
beforeProcessing afterProcessing beforeInsert beforeUpdate beforeDelete afterInsert afterUpdate afterDelete	DataAction Object
beforeOutput	none
