Forms Support
You can use the RadioButton in Template-driven and Reactive forms.
Template-Driven Forms
The template-driven forms enable you to bind the RadioButton to the model by using the ngModel
directive.
The following example demonstrates how to accomplish a two-way binding by using the ngModel
directive.
Reactive Forms
The FormGroup
decorator provides a way to render reactive forms. For more details, refer to the Angular documentation.
The following example demonstrates how to use the RadioButton in a reactive form.
Managing the RadioButton Disabled State in Reactive Forms
To disable the RadioButton component when working with reactive forms and Angular 15 or later, use the FormControl's disabled
property/option or disable()
method.
Angular 15 introduces a breaking change affecting the synchronization of
setDisabledState
with the model-DOM. This impacts components using thedisabled
attribute. As a result, thedisabled
property of the Kendo UI for Angular components used prior to Angular 15 is no longer working in reactive forms.
FormField Association
The Kendo UI for Angular FormField component enables you to group form-related elements, such as inputs, labels, hint and error messages, and configure their behavior.
The FormField automatically inserts the label before any form control. To position the RadioButton before a label, nest the two elements within a wrapper element.
The following example demonstrates how to use the RadioButton within a FormField with hint and error messages.
