To insert an embedded view from a prepared TemplateRef
in Angular, you would typically follow these steps:
Obtain a Reference to TemplateRef
: First, you need to have a TemplateRef
instance that represents the template you want to render. This is usually obtained using Angular's ViewChild
decorator to access the template within your component's class. For example:
@ViewChild('templateRef', { static: true, read: TemplateRef })
private templateRef: TemplateRef<any>;
Here, templateRef
is a template reference variable defined in your component's template.
Access ViewContainerRef
: Next, you need a ViewContainerRef
to define the location in the view where the template will be rendered. This can also be obtained using the ViewChild
decorator:
@ViewChild('viewContainerRef', { read: ViewContainerRef })
private viewContainerRef: ViewContainerRef;
viewContainerRef
is typically a reference to an ng-container
or any other container element in your component's template.
Create and Insert the Embedded View: With both TemplateRef
and ViewContainerRef
available, you can now create an embedded view and insert it into the view container using the createEmbeddedView
method:
this.viewContainerRef.createEmbeddedView(this.templateRef);
This method instantiates the template referenced by TemplateRef
and inserts the resulting view into the container specified by ViewContainerRef
.
Here's a complete example of how you might set up your component:
import { Component, ViewChild, TemplateRef, ViewContainerRef } from '@angular/core';
@Component({
selector: 'app-example',
template: `
<ng-template #templateRef>
<p>Hello, Embedded View!</p>
</ng-template>
<ng-container #viewContainerRef></ng-container>
`
})
export class ExampleComponent {
