Good morning!
When the pdf file is read by pdfViewer it takes a while for the document to appear.
As users never have patience, I would like to know if there is any event that is triggered when the entire document is shown.
Or another way of knowing.

Thank You
Marsenne

Hi,

Thanks for your inquiry and sorry for the late reply as weekend.
The principle of our Spire.PDFViewer preview PDF document is to first convert it to images, this process will cost some time. If your PDF contains more complex elements, it will take longer. Sorry there is no available event that can be triggered when the entire document is shown. I think if the control displays a picture indicating that the Pdf document is being loaded before the content is rendered, your customer will be more receptive. Look forward to your reply.

Sincerely,
Nina
