In LWC Is There A Way To Save Selected Radio Button Value To A Record
Introduction
In Salesforce Lightning Web Components (LWC), displaying picklist values as radio buttons in a Lightning record edit form is a common requirement. However, saving the selected values from the radio buttons to the record can be a challenge. In this article, we will explore the possible solutions to save the selected radio button value to a record in LWC.
Displaying Picklist Values as Radio Buttons
To display picklist values as radio buttons in a Lightning record edit form, you can use the lightning-radio-group component. Here's an example of how to do it:
<template>
<lightning-radio-group
name="color"
value={color}
onchange={handleChange}
options={[
{ label: 'Red', value: 'Red' },
{ label: 'Green', value: 'Green' },
{ label: 'Blue', value: 'Blue' }
]}
>
</lightning-radio-group>
</template>
<script>
import { LightningElement, track } from 'lwc';
export default class ColorRadioGroup extends LightningElement {
@track color = 'Red';
handleChange(event) {
this.color = event.detail.value;
}
}
</script>
Saving Selected Radio Button Value to a Record
To save the selected radio button value to a record, you need to use the save event of the lightning-record-edit-form component. However, the save event is not triggered when you use the lightning-radio-group component. Instead, you need to use the onchange event of the lightning-radio-group component to save the selected value.
Here's an example of how to save the selected radio button value to a record:
<template>
<lightning-record-edit-form
object-api-name="Account"
onsave={saveRecord}
fields-attributes={fieldsAttributes}
>
<lightning-radio-group
name="color"
value={color}
onchange={handleChange}
options={[
{ label: 'Red', value: 'Red' },
{ label: 'Green', value: 'Green' },
{ label: 'Blue', value: 'Blue' }
]}
>
</lightning-radio-group>
</lightning-record-edit-form>
</template>
<script>
import { LightningElement, track, api } from 'lwc';
import { ShowToastEvent } from 'lightning/platformShowToastEvent';
export default class ColorRadioGroup extends LightningElement {
@track color = 'Red';
handleChange(event) {
this.color = event.detail.value;
}
saveRecord(event) {
event.preventDefault();
const fields = event.detail.fields;
fields.Color__c = this.color;
this.template.querySelector('lightning-record-edit-form').submitFields(fields);
}
}
</script>
Using a Custom Form
Another approach to save the selected radio button value to a record is to use a custom form. You can create a custom form using the lightning-form component and use the onsubmit event to save the selected value.
Here's an example of how to use a custom form to save the selected radio button value to a record:
<template>
<lightning-form
onsubmit={saveRecord}
fields-attributes={fieldsAttributes}
>
<lightning-radio-group
name="color"
value={color}
onchange={handleChange}
options={[
{ label: 'Red', value: 'Red' },
{ label: 'Green', value: 'Green' },
{ label: 'Blue', value: 'Blue' }
]}
>
</lightning-radio-group>
</lightning-form>
</template>
<script>
import { LightningElement, track, api } from 'lwc';
import { ShowToastEvent } from 'lightning/platformShowToastEvent';
export default class ColorRadioGroup extends LightningElement {
@track color = 'Red';
handleChange(event) {
this.color = event.detail.value;
}
saveRecord(event) {
event.preventDefault();
const fields = event.detail.fields;
fields.Color__c = this.color;
this.template.querySelector('lightning-form').submitFields(fields);
}
}
</script>
