You need to modify the initial zoom percentage property of the PDF file itself. Using LEADTOOLS you can do it with few lines of code:
PDFInitialViewOptions myInitialViewOptions = new PDFInitialViewOptions();
myInitialViewOptions.AutoPrint = false;
myInitialViewOptions.CenterWindow = false;
myInitialViewOptions.ZoomPercent = 100;
pdfFile.InitialViewOptions = myInitialViewOptions;
pdfFile.SetInitialView(destinationFileName);
For more information about what other display properties you can modify, see this link:
