Hi Isaac/Alexander,
We have added support for setting ZoomMode in
PdfViewerControl itself as in PdfDocumentView in our latest Essential Studio
release and we have attached a simple sample on this.
Attachment: Sample-1047853779.zip
Run this sample, click the Fit- Width button in the left,
you can see that the document is now viewed in Fit-Width Mode.
Please, let us know if you need any further assistance.
Thanks,
Uthistran S.
