Alter the value by clicking a button within the DynamicRadioGroupModel in ng Dynamic Forms

I am working with ng-dynamic-form (version 6.0.4) and NG Bootstrap in Angular 6. I have a simple question.

When a button click event is triggered, I want to change the value in DynamicRadioGroupModel by using the "setValue()" method. However, I am facing an issue where the UI does not update after setting the value in the FormController. Can you help me solve this problem?

<div class="overflow-hidden content-margin container-fluid" style="width: 50%;">

<form class="form-horizontal" [formGroup]="formGroup">

    <dynamic-ng-bootstrap-form-control *ngFor="let formModelCtrl of formModel"
                               [group]="formGroup"
                               [layout]="formLayout"
                               [model]="formModelCtrl"
                               (blur)="onBlur($event)"
                               (change)="onChange($event)"
                               (focus)="onFocus($event)"
                               (ngbEvent)="onNgbEvent($event)"></dynamic-ng-bootstrap-form-control>

</form>

<button (click)="test()" type="button">Test</button>

<pre>{{formGroup.value | json}}</pre>

Answer №1

To update values, it is recommended to utilize the 'valueUpdates' Subject that is available in your DynamicFormsModel. In this scenario, the following code snippet should be effective:

   const radioGroup: DynamicRadioGroupModel<string> = 
this.dynamicFormService.findById('payment', this.formModel) as 
DynamicRadioGroupModel<string>; radioGroup.valueUpdates.next('cc');

The 'dynamicFormService' is the service used to generate the form group based on the model.

Regarding GitHub, an issue has been reported.
