Thank you for choosing Infragistics components!

Hello Vaishnavi,

Thank you for contacting Infragistics Developer support! 

To fire the event on copy, cut or paste you can use the the html editors events for that => help.infragistics.com/.../ui.igHtmlEditor. To fire the event when anything is typed you can attach the event to the current workspace. (reffer to the following post).

$(function() {
	var $htmlEditor = $("#htmlEditor");
	$htmlEditor.igHtmlEditor({
		width: '100%',
		cut: function() {
			triggerChangeEvent();
		},
		copy: function () {
			triggerChangeEvent();
		},
		paste: function() {
			triggerChangeEvent();
		},
	});
	
	var workspace = $($htmlEditor.selector + '_editor');
	
	$(workspace[0].contentWindow.document).on('keyup', function() {
		triggerChangeEvent();
	});

	function triggerChangeEvent() {
		$htmlEditor.trigger('change');
	}

	$htmlEditor.on('change', function() {
		alert('Change event is triggered');
	});
});

I am attaching sample if you have any additional questions please let me know.
