[Solved] PDF Viewer - How to remove current PDF documents

[Kalli Kaldi]

Hi all.

I'm using kendo-pdfviewer and loading it with a PDF I get from a web service.  The web service takes query parameters and returns a PDF as a Byte[] and I turn that into a base64 string and put that in the viewer.  Basic stuff ;)  Here's the element from my HTML:

        <kendo-pdfviewer style="height: 800px" [data]="pdfSrc" [tools]="pdfViewerTools">

          <app-pdfviewer-messages></app-pdfviewer-messages>

          <ng-template kendoPdfViewerBlankPageTemplate>

            <div class="blank-template">No data</div>

          </ng-template>

        </kendo-pdfviewer>

Now, if i.e. the user has a PDF in the viewer and wants to narrow the data with some extra parameters, and that result returns an empty PDF, I need to remove the previous PDF from the viewer.

I've tried to set [data] to null and undefined but that does not work. Any suggestions ?

Best regards,
