     //scheduler.load(url,callback);
     scheduler.load("data.php");

<data>
	<event id="2">
		<start_date>2009-05-24 00:00:00</start_date>

DTSTART, DTEND - used as start and end of event DESCRIPTION - used as text of event all attriubutes of event from iCal structure mapped to the properties of event with the same name

Scheduller includes dataProcessor and can use it to sync. with server ( if you want to implement custom server side logic you can check dataProcessor article )

		scheduler.init('scheduler_here',null,"month");
		scheduler.load("events.php?uid="+scheduler.uid());
 
		var dp = new dataProcessor("events.php");
		dp.init(scheduler);

	include ('dhtmlxConnector/codebase/scheduler_connector.php');
 
	$res=mysql_connect("localhost","root","");
	mysql_select_db("sampleDB");
 
	$calendar = new SchedulerConnector($res);
	$calendar->render_table("events","id","event_start,event_end,event_text","type");

The third parameter must have 3 mandatory fields:

• event field mapped to start date;
• event field mapped to end date;
• event field mapped to event text.

For more details about connector usage - you can check Connectors documentation

• PHP - http://dhtmlx.com/docs/download/dhtmlxConnector_php.zip
• .Net - http://dhtmlx.com/docs/download/dhtmlxConnector_net.zip
• Java - http://dhtmlx.com/docs/download/dhtmlxConnector_java.zip
• RubyOnRails - http://support.dhtmlx.com/x-files/samples/ruby_scheduler.zip

By default scheduler load all data at once. It may be problematic in case of big event collections. In such situation dynamical event loading can be used - in case of dynamical loading, scheduler will load only part of event, necessary to fill current viewable area.

    scheduler.setLoadMode("month");
    scheduler.load("some.php");

Possible values are

• year
• month
• day

If setLoadMode was used , scheduler will generate calls as

    some.php?from=DATEHERE&to=DATEHERE

where DATEHERE - will be a valid date values, format of which is defined by scheduler.config.load_date (%Y-%m-%d by default)

In case of “month” mode - calendar will request data for each month ( it is clever enough, to cache already used data - so requests will be sent only once per month )

If you are using dhtmlxConnector at server side, library is aware of such use-case and can be used in dyn. mode without any additional server side settings.

If you need to load data dynamically from multiple sources - it can be organized by using related extension

You can include loading indicator by using

      scheduler.config.show_loading=true;

If you can change loading image to different one - just replace imgs/loading.gif with different one
