  Hi.

  We are currently using your C1PrintPreviewControl and C1PrintDocument in our project. I would like to inquire if it is possible to automatically refresh the display in C1PrintPreviewControl when adding a new page using the C1PrintDocument.NewPage method.

  Specifically, our goal is to allow users to view all the pages created up to that point in the document, rather than waiting for the entire document—potentially 50 to 100 pages—to be generated and displayed only after calling the EndDoc method. This enhancement would significantly improve the user experience by providing immediate feedback as new pages are added.

  Thank you for your assistance.

  Best regards,

  Hello,

  Apologies for the inconvenience caused by the delayed response.

  Currently, your requirement is not possible using the C1PrintPreviewControl, i.e., after a document is created, no display refresh method or event is called.

  • Specifically, our goal is to allow users to view all the pages created up to that point in the document, rather than waiting for the entire document …
    
    A better approach for your use case could be to virtualize the document generation in C1PrintPreviewControl. This would allow the document to be displayed in the preview control while continuing to generate in the background, making the experience smoother and more efficient.
    
    Please let us know if this approach aligns with your requirements. We are currently discussing with the team whether it is feasible to implement virtualization for document generation within C1PrintPreviewControl.
    
    Thank you for your patience.

  Regards,
  
  Uttkarsh.

  Thank you for the suggestion. I agree that virtualizing the document generation in C1PrintPreviewControl would be a much better approach and would indeed make the experience smoother and more efficient. It aligns perfectly with our requirements.

  Could you please provide an estimated timeline for when this could be implemented? Additionally, could you clarify which versions this will be supported in?

  Thanks again for your help and looking forward to your response.

  Hello,

  As per the team, it is already available in C1PrintPreviewControl. The document is displayed while it is loading in background. Please refer to the attached video and sample.
