Heres how iam setting the URL, This method will be called when i need to show the component

public show(): void {
        this.visible = true;
        this.visibleAnimate = true;
        this.DocURL = this.sanitizer.bypassSecurityTrustResourceUrl(this.src);

 constructor(private sanitizer: DomSanitizer) {
        this.visible = false;
        this.visibleAnimate = false;

        this.DocURL = this.sanitizer.bypassSecurityTrustResourceUrl( + "/pdf.pdf");

Heres the HTML Part

  <div style=" height:650;width:870">
          <object width="870" height="650" type="application/pdf" [data]="DocURL" id="doc" #doc>
            <p>Not able to display the document</p>
       <div style="display:none">
           <iframe id="fred" #fred style="border:1px solid #666CCC" title="PDF in an i-Frame" [src]="DocURL" frameborder="1" scrolling="auto" height="1100" width="850" ></iframe>

The URL iam supplying will be dynamic


Your URL does not have a protocol. Try the following:

this.DocURL = this.sanitizer.bypassSecurityTrustResourceUrl(window.location.protocol + '//' + + "/pdf.pdf");
