Hello Pradnya,

Please follow the steps below.

1. Add a new tab called Spire.PdfViewer to Toolbox, please refer to PDFViewer1.jpg.
2. To choose Items for the tab, then you will see a dialog box (PDFViewer2.jpg), to browse and add Spire.PdfViewer.Forms.dll.
3. Now you can see "Spire.PdfViewer " control in Toolbox, just like PDFViewer3.jpg.

If there are any questions, welcome to get it back to us.
Sincerely,
Gary

Hello ,

Thank you for your great help !!!!!!!!!!!!!

Now i able to add the "Spire.PdfViewer" but unable to get the function like export image,Page Operations..

Does it Support Pdf Merging Functionality means can we merge two pdf Document together into single pdf Document .?

Also Does it support for Markup Functionality means can we copy only Markup (Clouds, Highlighted Text , Sticky Notes) from one pdf Document and apply these Markup to another pdf Document .

Thanks and Regards,

Hello Pradnya,
Sorry for the late reply.
Question:Now i able to add the "Spire.PdfViewer" but unable to get the function like export image,Page Operations.
Answer: Please refer to the following method to export image, and you could also get more demos about PdfViewer below Demo from http://www.e-iceblue.com/Introduce/pdf- ... #PDF2Image
Code: Select all
int currentPage=this.pdfDocumentViewer1.CurrentPageNumber;
Bitmap image=this.pdfDocumentViewer1.SaveAsImage(currentPage-1);
image.Save(fileName);

Question:Does it Support Pdf Merging Functionality means can we merge two pdf Document together into single pdf Document ?
Answer: Sorry that our PdfViewer product doesn't support it, but you could use our Spire.Pdf product to achieve it and refer to the following method.
Code: Select all
String[] files = new String[]
{
@"..\..\test.pdf",
@"..\..\test1.pdf"
};
//open pdf documents           
PdfDocument[] docs = new PdfDocument[files.Length];
for (int i = 0; i < files.Length; i++)
{
docs[i] = new PdfDocument(files[i]);
}
//import PDF pages
for (int i = 0; i < docs[1].Pages.Count; i = i + 2)
{
 docs[0].InsertPage(docs[1], i);
}
docs[0].SaveToFile(@"..\..\Result.pdf",FileFormat.PDF);

Question:Also Does it support for Markup Functionality means can we copy only Markup (Clouds, Highlighted Text , Sticky Notes) from one pdf Document and apply these Markup to another pdf Document .
Answer:
Sorry that our PdfViewer product doesn't support it, but you could use our Spire.Pdf product to achieve it and refer to the following method. But regarding Highlighted Text, sorry that at present we couldn’t get the text which is highlighted only get highlight as the Highlight Text Markup itself has no text property, which highlights the text that exists in pdf.
Code: Select all
PdfDocument pdfdoc = new PdfDocument();
pdfdoc.LoadFromFile(@"..\..\PDFviewer.pdf");
PdfDocument newpdf = new PdfDocument();
PdfPageBase newpage = newpdf.AppendPage();
foreach (PdfPageBase page in pdfdoc.Pages)
   {
   for (int i = 0; i < page.AnnotationsWidget.Count;i++ )
       {
          newpage.AnnotationsWidget.Add(page.AnnotationsWidget[i]);
        }
    }
newpdf.SaveToFile(@"..\..\result.pdf",FileFormat.PDF);
