Events

• Loading Events:
  • onXLS - occurs before sending data request to server
  • onXLE - occurs after sending data request to server

• Data manipulation:
  • onBeforeAdd - item adding is initiated
  • onAfterAdd - item adding is finished
  • onBeforeDelete - item deleting is initiated
  • onAfterDelete - after deleting is finished

dhtmlXDataStore allows to handle different events using its event handling system. You can attach several handlers to the same event and detach them using two respective methods:

• attachEvent() - to attach event.
  
  

  function my_handler(){ do_something(); };
  data.attachEvent("onSomeEvent",my_handler);

  • evName - the name of an event;
  • evHandler - the user-defined event handler.

• detachEvent() - to detach event.
  
  

  var myevent = data.attachEvent("onSomeEvent",my_handler);
    ...
  data.detachEvent(myevent); // the unique id of the event handler

• Events' names are case-insensitive.
• All events with subword 'onbefore' can be blocked. To block default event processing you should return false within the appropriate event handler.
