A set of radio buttons

Include the ext/dhtmlxscheduler_editors.js file to use the control in the lightbox

var priorities = [
    { key: 1, label: 'High' },
    { key: 2, label: 'Medium' },
    { key: 3, label: 'Low' }
scheduler.locale.labels.section_priority = 'Priority';
scheduler.config.lightbox.sections = [
    { name:"text", height:50, map_to:"text", type:"textarea", focus:true },
    { name:"priority", height:58, options:priorities, 
                map_to:"priority", type:"radio", vertical:true},
    { name:"time", height:72, type:"time", map_to:"auto"}

To add the Radio control to the lightbox, follow these steps:

  1. Include the 'ext/dhtmlxscheduler_editors.js' extension file on the page:
    <script src="../codebase/ext/dhtmlxscheduler_editors.js"></script>
  2. Add the section to the lightbox configuration:
    scheduler.config.lightbox.sections = [
        { name:"description", ... },
        { name:"radiobutton", height:58, options:priorities, 
        map_to:"priority", type:"radio", vertical:true},
        { name:"time", ...}
  3. Set the label for the section:
    scheduler.locale.labels.section_priority = 'Priority';

The following properties are mostly important and commonly set for the 'radio' control (see the full list here):

Populating the control with data

Generally, to set values for the radio buttons you should use the options parameter:

scheduler.config.lightbox.sections = 
    {   name:"alert", type:"select", 
            { key: 1, label: 'High' },
            { key: 2, label: 'Medium' },
            { key: 3, label: 'Low' }

Items in the options parameter must have 2 mandatory properties:

  • key - the option's id
  • label - the option's label

Getting the radio buttons values from the server

To set values for radio buttons, using data retrieved from the server, use the serverList method:

scheduler.config.lightbox.sections = [
    {name:"description", ...},
    {name:"priority", map_to:"priority", type:"radio", 
    {name:"time", ...}

The data response for the load method should contain a collection with the server list name specified in JSON of the following format:

          "start_date":"2019-03-02 15:00:00",
          "end_date":"2019-03-04 16:00:00",
          "start_date":"2019-03-02 17:00:00",
          "end_date":"2019-03-04 18:00:00",
          "text":"Performance review",
   "collections": {      "type":[               {"value":1,"label":"Low"},         {"value":2,"label":"Medium"},         {"value":3,"label":"High"}      ]   }}

If you use PHP Connector library, the server code may look like the following:

    include ('../../common/config.php');
    $list = new JSONOptionsConnector($res, $dbtype);
    $scheduler = new JSONSchedulerConnector($res, $dbtype);
    $scheduler->set_options("type", $list);

Note, you can use the updateCollection method to update the list of retrieved options

Event handling for the Radio Control

By default, dhtmlxScheduler API doesn't provide any specific event handlers for radio buttons in the Scheduler lightbox.

But you can assign a click handler for the Lightbox Radio controls like this:

1. Get radio elements after the lightbox will be opened.

scheduler.attachEvent("onLightbox", function(){
    var node = scheduler.formSection("type").node;
    var radios = node.getElementsByTagName("input");

2. Attach the onclick event to the found radio buttons of Lightbox.

scheduler.attachEvent("onLightbox", function(){
    for(var i = 0; i < radios.length; i++){
      radios[i].onclick = onRadioClick; 

3. Finally, you should specify a function that will be executed after clicking the radio button.

function onRadioClick(event){
    var e = event || window.event,
        node = this;
