DevExtreme jQuery - Overview
The RadioGroup is a widget that contains a set of radio buttons and allows an end user to make a single selection from the set.
The following code adds a simple RadioGroup to your page. Here, the value option specifies the initially selected radio button.
<div id="radioGroupContainer"></div>
$(function() {
$("#radioGroupContainer").dxRadioGroup({
dataSource: ["Low", "Normal", "Urgent", "High"],
value: "Low"
});
});If your data is an array of objects, bind it to the RadioGroup using the displayExpr and valueExpr options. displayExpr specifies which data source field provides texts for buttons; valueExpr specifies which data source field provides values to be written to the value option when a button is selected. Leave valueExpr unspecified if you need the entire data object to be written to the value option.
var dataItems = [
{ text: "Low", color: "grey" },
{ text: "Normal", color: "green" },
{ text: "Urgent", color: "yellow" },
{ text: "High", color: "red" }
];
$(function() {
$("#radioGroupContainer").dxRadioGroup({
dataSource: dataItems,
displayExpr: "text",
// valueExpr: "color",
value: dataItems[1]
});
});The RadioGroup widget supports horizontal (default for tablets) and vertical (default for other devices) layouts. To change the layout for all types of devices, specify the layout option.
$(function() {
$("#radioGroupContainer").dxRadioGroup({
dataSource: ["Low", "Normal", "Urgent", "High"],
layout: "horizontal" // or "vertical"
});
});
