Попробуйте следующим образом:
test = " HTML Content ";
TestString = `<div>This is test code, i am trying to bind/render ${this.test} code with angular..,</div>`

Если вы хотите оценить шаблон из строки внутри компонента , Вы можете создать свою собственную директиву, которая будет это делать:
compile.directive.ts
import {
Compiler, NgModule, Component, Input, ComponentRef, Directive,
ModuleWithComponentFactories, OnChanges, Type,
ViewContainerRef
} from '@angular/core';
import { CommonModule } from '@angular/common';
@Directive({
selector: '[compile]'
})
export class CompileDirective implements OnChanges {
@Input() compile: string;
@Input() compileContext: any;
compRef: ComponentRef<any>;
constructor(private vcRef: ViewContainerRef, private compiler: Compiler) {}
ngOnChanges() {
if(!this.compile) {
if(this.compRef) {
this.updateProperties();
return;
}
throw Error('You forgot to provide template');
}
this.vcRef.clear();
this.compRef = null;
const component = this.createDynamicComponent(this.compile);
const module = this.createDynamicModule(component);
this.compiler.compileModuleAndAllComponentsAsync(module)
.then((moduleWithFactories: ModuleWithComponentFactories<any>) => {
let compFactory = moduleWithFactories.componentFactories.find(x => x.componentType === component);
this.compRef = this.vcRef.createComponent(compFactory);
this.updateProperties();
})
.catch(error => {
console.log(error);
});
}
updateProperties() {
for(var prop in this.compileContext) {
this.compRef.instance[prop] = this.compileContext[prop];
}
}
private createDynamicComponent (template:string) {
@Component({
selector: 'custom-dynamic-component',
template: template,
})
class CustomDynamicComponent {}
return CustomDynamicComponent;
}
private createDynamicModule (component: Type<any>) {
@NgModule({
// You might need other modules, providers, etc...
// Note that whatever components you want to be able
// to render dynamically must be known to this module
imports: [CommonModule],
declarations: [component]
})
class DynamicModule {}
return DynamicModule;
}
}
Использование:
@Component({
selector: 'my-app',
templateUrl: './app.component.html',
})
export class AppComponent {
name = 'Product Name :'
price = '3'
template: string = `{{ name }} <b>{{ price }}$</b>`;
}
HTML:
<div class="product">
<ng-container *compile="template; context: this"></ng-container>
</div>
