this should be very simple, just use isLoaded in your HTML:

<ngx-spinner *ngIf="!isLoaded" bdColor="rgba(51, 51, 51, 0.8)" size="default" type="ball-spin-clockwise">
    <p style="color: rgb(33, 221, 118)">Be Patince PDF is loaded. </p>
</ngx-spinner>

and

this.api.tbl_report_pdf_data_one(this.activeRoute.snapshot.params.pdfid).subscribe((res) => {
  this.data = res;
  this.isLoaded = true;
})

Sorry, but your code is not workable. I have tried your code. Actually I have imported NgxSpinnerService and use (this.SpinnerService.show(); )which is show the loader. as well added (this.SpinnerService.hide ();)but this not workable and that my concern how it can not worked. – Mishti Feb 14 '22 at 14:45
Here the url I have prefer to add loader https://www.c-sharpcorner.com/article/how-to-add-loaderspinner-in-angular-8-application/ – Mishti Feb 14 '22 at 14:46
so this NgxSpinner is very strange but ok... does it shows up? and doses the subscribe() work? please add a console.log() before this.SpinnerService.hide(); – Zerotwelve Feb 14 '22 at 15:10
