To create a form validation for angular you can use one of these two methods:
Method one using ngmodel use the angular ngmodel form validation
Use form FormControl Formcontrol
I hope that can help you to resolve your issue.

I have used ngx-mask dynamically in my app by assigning a variable to it.
This is nullable variable and input shows undefined when the variable is null or undefined.
This is happening after I upgrade Angular from ver-8 to ver-9.
It was working fine on Angular 8.
I want mask in input does nothing when the variable is null or undefined. Please help me.
I find the solution.
The problem was I was using value instead of ngModel to apply value on input.
When I changed it to ngModel, the issue resolved.
Help please,
I tried to fix it without success. I'm using Ionic framework and Angular. I have a form which is opened when I click on a Sidemenu. So the problem is when I add a formControllerName on the input field it modified my design's form. I don't understand why these input can change my form. I imported everything in my module's page where I needed.
my form without formControlName
form_1
my form with formControlName
Form_2
Input
Hi my angular form is getting hanged when am try to scroll up and down and try to select drop down options, selecting items in list control. My form contains input controls which has regex patterns, controls. All these controls are in my child html form.
And if i clear cache its working fine.
Please suggest me to fix this issue.
Calling a method function from direct html can be costlier Operation which might have called your application function multiple times apart of life cycle hooks.
It's better to use always variable instead of functions if you are not using it already. Please share your code snippet or stackblitz url for better help from community
I need to have an input field with an arrow on the right so when I press on the arrow I have the bahaviour of a select tag ( a dropdown list of options). I was wondering if it's possible to do this in HTML/Angular 6... I found the solution of a datalist but it's not actually the result I'm looking for because with this solution if I enter some value in the input, which is not present in the datalist, and then click on the arrow anything display because datalist filters what to display depending on the input value.
Hope it's clear enough.
Taking account that you can use a library or an UI framework, I suggest you the following options:
Angular Material Select Component
The google's UI framework to Angular applications.
Pros: Acessbility and responsivity are concerns of the framework, easy integration with Angular
Cons: The values of select can't be filtered
https://material.angular.io/components/select/overview
Angular Material Autocomplete component
Another component of google's UI framework. It's not a pure select, but it can be adapted as a combobox with filtering.
Pros: Acessbility and responsivity are concerns of the framework, easy integration with Angular
Cons: As it's not a pure select component, so maybe you would have to adapt it.

I am using this Plunkr. It displays a list of products. When I click on remove button, the items which are checked should be removed from the list.
<button ng-click="onClick()" class="k-button">Remove</button>
I have tried various things however, nothing is working. I am not exactly getting what logic should go in the following logic
$scope.onClick = function () {
}
I know it is something very simple however, I am not able to get it. Any help would be appreciated.
If you ask about logic, i will try to explain it here..
First inside onClick function get your gird's datasource variable, then find all selected checkboxes and use jquery each to iterate over each checkbox and find closest data-uid attribute. Every grid row has uid in its DOM, with this uid value get kendo observable object from datasource with getByUid method.
Last using datasource pass this observable object to remove method of datasource.
This is Kendo datasource API, hopes it helps you to write the code..
