The Basics
Make sure you followed all the steps from the introductory article on Telerik UI for PHP—include the autoloader, JavaScript, and CSS files.
Initialization
The example below demonstrates how to initialize the RadioGroup by using the default radiogroup
tag.
$radiogroup = new \Kendo\UI\RadioGroup('radiogroup');
$radiogroup->value("one");
$radioFirst = new \Kendo\UI\RadioGroupItem();
$radioFirst->label("Agree")
->value("one");
$radiogroup->addItem($radioFirst);
$radiogroup->addItem("Disagree");
echo $radiogroup->render();
Features
Enable and Disable RadioGroup
You can configure the RadioGroup to be initially disabled by using its enable
property. The RadioGroup can also be disabled or enabled at any time with JavaScript by using the enable()
method with a Boolean argument. For more information on the enable
method of the RadioGroup, refer to the RadioGroup API.
The following example demonstrates how to enable and disable the RadioGroup.
$radiogroup = new \Kendo\UI\RadioGroup('radiogroup');
$radiogroup->value("Agree")
->enabled(false);
$radiogroup->addItem("Agree");
$radiogroup->addItem("Disagree");
echo $radiogroup->render();
Labels
The example below demonstrates how to configure label
and labelPosition
to the RadioGroup.
$radiogroup = new \Kendo\UI\RadioGroup('radiogroup');
$radiogroup->labelPosition("before")
->value("one");
$radioFirst = new \Kendo\UI\RadioGroupItem();
$radioFirst->label("Female")
->value("one");
$radioSecond = new \Kendo\UI\RadioGroupItem();
$radioSecond->label("Male")
->value("two");
$radiogroup->addItem($radioFirst);
$radiogroup->addItem($radioSecond);
echo $radiogroup->render();
Layout
The RadioGroup widget supports two types of layout
- "horizontal" and "vertical". By default the radio buttons are rendered vertically.
The following example shows how to set the RadioGroup layout:
$radiogroup = new \Kendo\UI\RadioGroup('radiogroup');
$radiogroup->->value("Agree")
->layout("horizontal");
$radiogroup->addItem("Agree");
$radiogroup->addItem("Disagree");
echo $radiogroup->render();
Event Handling
Subscribe to Events
You can subscribe to all events exposed by Kendo UI RadioGroup by the handler name.
<?php
$radiogroup = new \Kendo\UI\RadioGroup('radiogroup');
$radiogroup->value("one");
$radioFirst = new \Kendo\UI\RadioGroupItem();
$radioFirst->label("Female")
->value("one");
$radioSecond = new \Kendo\UI\RadioGroupItem();
$radioSecond->label("Male")
->value("two");
$radiogroup->addItem($radioFirst);
$radiogroup->addItem($radioSecond);
$radiogroup->focus("onFocus")
->select("onSelect")
->change("onChange");
echo $radiogroup->render();
?>
<script>
function onChange(e) {
// handle the change event
}
function onFocus(e) {
// handle the focus event
}
function onSelect(e) {
// handle the select event
}
</script>
Reference
Existing Instances
To reference to an existing RadioGroup instance, use the jQuery.data()
method. Once a reference is established, use the API to control its behavior.
The following example demonstrates how to access an existing RadioGroup instance.
//Put this after your Kendo RadioGroup tag declaration
<script>
$(function() {
// Notice that the Name() of the RadioGroup is used to get its client-side instance
var radiogroup = $("#radiogroup").data("kendoRadioGroup");
});
</script>
