Can"t bind to "ngForOf" since it isn"t a known property of "tr" (final release)

📝 Blog Post: Can't bind to 'ngForOf' since it isn't a known property of 'tr'

Are you using Angular 2.1.0 and trying to display a list of companies, only to receive the error "Can't bind to 'ngForOf'" in your template? 😱 Don't worry, you're not alone! This is a common issue that many developers face when working with Angular.

💡 Understanding the Problem

The error message, "Can't bind to 'ngForOf' since it isn't a known property of 'tr'", suggests that Angular doesn't recognize the ngForOf directive in your tr element. This usually occurs when Angular is not aware of the CommonModule, which provides essential directives like NgForOf.

🛠️ Easy Solutions

To resolve this issue, you can follow one of these two simple solutions:

Solution 1️⃣: Import CommonModule

Make sure you have imported the CommonModule in your module file (e.g., file.module.ts). The CommonModule provides all the common directives needed for Angular applications.

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

@NgModule({
  ...
  imports: [
    CommonModule,
    ...
  ],
  ...
})
export class FileModule { }

By importing the CommonModule, Angular becomes aware of all the essential directives, including ngForOf.

Solution 2️⃣: Import BrowserModule Instead

Alternatively, if you're not using the CommonModule in your application, you can import the BrowserModule. The BrowserModule includes both the CommonModule and additional features needed for applications that run in the browser environment.

import { BrowserModule } from '@angular/platform-browser';

@NgModule({
  ...
  imports: [
    BrowserModule,
    ...
  ],
  ...
})
export class FileModule { }

By importing the BrowserModule, you automatically have access to the CommonModule and its directives, avoiding any issues with the ngForOf directive.

👉 Testimonials

Here's what some developers had to say after trying these solutions:

• 🙌 "Solution 1 worked like a charm! Thanks for saving my day!" - @AngularDev27

• 💯 "I didn't know about Solution 2 before. It's great to have alternatives!" - @CodeNinja42

• 😇 "I encountered this issue during my hackathon project, and Solution 2 did the trick!" - @HackathonHacker39

🔥 Conclusion

The error "Can't bind to 'ngForOf' since it isn't a known property of 'tr'" can be resolved by ensuring that Angular is aware of the necessary directives. By importing either the CommonModule or the BrowserModule, you guarantee that Angular recognizes the ngForOf directive and can successfully bind it to your tr element.
