Can t bind to ngclass since it isn t a known property of input

Question

Can you tell me Can't bind to 'ngclass' since it isn't a known property of 'input'?

Answer 1

This error occurs because Angular does not recognize ngClass on an <input> element. The likely reasons are:

Missing CommonModule Import (if using Angular modules)

Ensure CommonModule is imported in the module where the component is declared.

import { CommonModule } from '@angular/common';

Missing BrowserModule Import (for standalone apps)

Ensure BrowserModule is imported in app.module.ts.

Typo or Incorrect Usage

Ensure ngClass is correctly used with square brackets ([ngClass]) and bound to a valid object or expression.

<input [ngClass]="{'class-name': condition}" />

Component Not Declared in the Right Module

Ensure the component using ngClass is declared in a module that imports CommonModule.
