### LoadInViewer
In order for LoadInViewer to function, your WebHTMLViewer must have the following code in its Shown event:
## Examples
### Page Numbering
For page numbering, the variables %x and %y are parsed when the PDF is rendered. %x corresponds to the current page while %y corresponds to page count.
The following example will show the current page’s number and total page count in the center position of both the header and footer.
```
doc.Template.HeaderLeft = "Page %x of %y"
```
### Saving PDFs on the Server
Defining the UploadPath property will cause generated PDFs to be automatically saved on your server in the path you provide with the following structure:
`
/UploadPath/Session.Identifier/Year/Month/Day/Filename.PDF
`
Data is not retained in the GraffitiWebFile object to reduce memory usage, and is written directly to the file as it is received.
If UploadPath is Nil then file data will not be transferred back to the server and DocumentReady is only an indicator that you may then safely call the Download, LoadInViewer, and Print methods for client-side functionality.
