The app component contains an example form FormGroup which contains a single boolean field with a requiredTrue validator to make a checkbox field required. The app component uses a FormBuilder to create an instance of a FormGroup that is stored in the form property. The component contains a convenience getter property f to make it easier to access form controls from the template. So for example you can access the confirmPassword field in the template using f.

The app component template contains the html markup for displaying the example required checkbox form in the browser. The form element uses the [formGroup] directive to bind to the form FormGroup in the app component above. Validation messages are displayed only after the user attempts to submit the form for the first time, this is controlled with the submitted property of the app component.

So, it could be 3,4,5 or more checkboxes on the form. That could be a textbox, dropdown or radio button list types in contingent to the checked item and they are required fields.

In this article, I will share how to accomplish the following task. Instead of displaying the required field message next to each form element, we can program the form to display an error indicator by using Cascading Style Sheets CSS selector.

For instance, we can use the ::after selector to append an asterisk next to the label in red font. Or make the form control border red color if the control has ng-invalid class. The radio button list is a little tricky, based on the sample application, we can utilize the CSS combinators and pseudo-classes in Listing 3 to append an asterisk next to the label.

Basically, the selector will select all the labels under a form control with invalid state and append an asterisk next to it with red font. Figure 2 shows the form control output using the CSS in listing 3. Listing 4 shows how to utilize the FormBuilder. The first three FormControls are required and the email must match the regular expression requirement.

The programmingLanguage values type is a FormArraywhich will host an array of available programming languages using Checkboxes and another input type. Shown in listing 5 is the sample object and data that the application will be using.

The next step is to populate the programming language FormArray. Initially, the code will loop through the properties of programmingLanguageList object and populate the langControlMetada object.

The Checkbox label will come from the Item. The associateControlLabel property will serve as a placeholder attribute for the input element. By default, the associateControlType will be a textbox, in this example, the application will display a radio button list if PHP option is checked, and a dropdown list if Other option is checked.

The purpose of the associateControlData property is to hold the data source for the radio button and dropdown elements. The next step is to create two FormControlsone for the Checkbox element and one for the associated element. By default, the associated element is disabled. Then, insert the child controls created previously into a FormGroup.

The key will be identical to the Checkbox and associate element name. Finally, insert the FormGroup instance into the programmingLanguage object. It uses the NgFor directive to build the "Your favorite programming language" section with the properties from the langControlMetada object.

The purpose of the updateValueAndValidity method is to update the value and validation status of the control. On the other hand, unchecking the checkbox will clear the value of the associate element, disabled it and remove the validator.

Once the form is valid, the submit button will become clickable. Shown in listing 10 is the code for the button click event. The code will iterate the programmingLanguage control which is the FormArray to get the checked checkbox and associated control values in the FormGroup.

In order to get the checkbox id, first, get the first control name from the FormGroup. Then, remove the static text and parse it to the number.A while ago, we looked at creating our first form in Angular.

We typically would handle this scenario with a checkbox list. In this post, we will build a checkbox list with Angular but create it dynamically from a list and add some additional validation rules.

Here is what our UI will look like:. For our use case, we have a list of orders for a user to choose from. The business rules state that the user must select at least one order before being able to submit the form. For our example, the orders object will be pretty straightforward.

A real-world scenario this data would likely come from an API. With our orders list, we are going to create our checkboxes dynamically. The Reactive Forms API has some excellent benefits with using Observables and Reactive programming but also has an excellent natural way to declare form inputs in our TypeScript dynamically. Reactive Forms compose of primarily three Class types.

First FormGroups which typically represents a single form. A FormGroup is typically made of many FormControl s. A FormControl usually represents a single input in a form. Lastly is the FormArray. The FormArray is used to represent a collection of FormControl s that are interrelated. For our example, we will use all of these Classes. Specifically, the FormArray provides an easy way to create a list of checkbox controls.

The FormArray simplifies getting values of all as a collection and validate our checkbox list. First, we are going to start with creating our FormGroup in our TypeScript and Template for the component. In our component, we use the FormBuilder service to create our FormGroup that we will declare in the template.

This is the glue for our template to communicate with the TypeScript code. On the ngSubmit event we will log the form value. We next need to add our dynamic list of checkboxes. In our example, we create an array of form controls. Each form control is representing a single checkbox with a starting value of false. We set the first control to true, so the first item in our list is checked. Next, we pass the array into the constructor of our FormArray in the form builder.

The form array treats each checkbox as part of a collection of controls.

The FormArray creates an easy to use API to set the value and check the validation of the entire collection instead of having to iterate through each FormControl.
