Displaying PDF document

Question

Hi there, I am currently working on a project where you can upload and view a PDF document. So far I have the upload PDF function completely working. The only issue I am having is when I click on my View LinkButton I get an error: "Input string was not in a correct format.". I feel as though my LinkButton is properly linked but the error occurs when it hits: 

int id = int.Parse((sender as LinkButton).CommandArgument);

Also, when I use: //var id = ((LinkButton)sender).CommandArgument;    instead, I'm not getting errors, but nothing is showing up.

 

The code for my LinkButton is shown here: 

<asp:LinkButton ID="lnkView" runat="server" Text="View" OnClick="Button2_Click" CommandArgument='<%# Eval("ID") %>'></asp:LinkButton> 

 

Any help would be GREATLY appreciated!

Thanks you,

M

So now, when I click on the linkbutton view for viewing the PDF file; a message box displays with the message "File does not being with '%PDF-'". Anyone have any suggestions as to why it says that? The files that I am trying to view ARE .pdf files.

Hi Chris,

 

This article demonstrates how to view PDF file from web browser using a asp.net PDFViewer, not sure if this will help you, but you can check:
