JavaScript/jQuery RadioGroup - Overview
The RadioGroup is a UI component 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 property specifies the initially selected radio button.

JavaScript
<div id="radioGroupContainer"></div>
$(function() {
$("#radioGroupContainer").dxRadioGroup({
dataSource: ["Low", "Normal", "Urgent", "High"],
value: "Low"
});
});Angular

TypeScript
<dx-radio-group
[dataSource]="dataSource"
value="Low">
</dx-radio-group>

dataSource = ["Low", "Normal", "Urgent", "High"]

const dataSource = ['Low', 'Normal', 'Urgent', 'High'];
class App extends React.Component {
render() {
return (
<RadioGroup
dataSource={dataSource}
value="Low"
/>
);
}
}
export default App;If your data is an array of objects, bind it to the RadioGroup using the displayExpr and valueExpr properties. displayExpr specifies which data source field provides texts for buttons; valueExpr specifies which data source field provides values to be written to the value property when a button is selected. Leave valueExpr unspecified if you need the entire data object to be written to the value property.
