Angular 2 Access Ng Content Within Component

When working on Angular projects, it's common to encounter situations where you need to access and manipulate content within your components. In this article, we'll dive into how you can efficiently access Ng content within an Angular 2 component.

### What is Ng Content?
Ng content refers to the content that gets projected into a component using Angular's content projection feature. This allows you to inject HTML elements and components into a designated placeholder within another component.

### Accessing Ng Content in Angular 2 Component:
To access Ng content within an Angular 2 component, you can use the **ContentChild** and **ContentChildren** decorators provided by Angular.

#### 1. Using ContentChild:
The **ContentChild** decorator allows you to access the first instance of a projected content within your component. Here's a simple example:

Typescript

import { Component, ContentChild } from '@angular/core';

@Component({
  selector: 'app-custom-component',
  template: `
    <div>
      
    </div>
  `
})
export class CustomComponent {
  @ContentChild('myProjectedElement', { static: true }) projectedElement: ElementRef;
}

In the above example, we are accessing the projected content with the template reference variable 'myProjectedElement'. We use **ElementRef** to access the native element of the projected content.

#### 2. Using ContentChildren:
If you want to access multiple instances of projected content, you can use the **ContentChildren** decorator. Here's an example:

Typescript

import { Component, ContentChildren, QueryList } from '@angular/core';

@Component({
  selector: 'app-custom-list',
  template: `
    <ul>
      
    </ul>
  `
})
export class CustomListComponent {
  @ContentChildren('myProjectedItems') projectedItems: QueryList;
}

In this example, we are accessing multiple instances of the projected content using **QueryList** instead of a single element.

### Summary:
Accessing Ng content within an Angular 2 component is essential for building dynamic and interactive applications. By utilizing the **ContentChild** and **ContentChildren** decorators, you can easily retrieve and interact with the projected content.

Remember, understanding how to access Ng content opens up a whole new world of possibilities for enhancing the functionality and user experience of your Angular applications.

Hopefully, this article has provided you with a clear understanding of how to access Ng content within Angular 2 components. Happy coding!
