Hi, i'm trying your control suite and i started to try the control in subject following the demo ccode of your website and all works fine if i use the default document ( <PdfjsProcessingSettings File="prev.pdf">
</PdfjsProcessingSettings>). But what should i do if i want to pass the file name in runtime mode dynamically? I tried this:
.ASPX FILE
<%@ Page Language="VB" AutoEventWireup="false" CodeBehind="Default.aspx.vb" Inherits="PdfProva._Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

</script>
<telerik:RadStyleSheetManager id="RadStyleSheetManager1" runat="server" />
</head>
<body>
<form id="form1" runat="server">
<telerik:RadScriptManager ID="RadScriptManager1" runat="server">
<Scripts>
<asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js" />

<asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQueryInclude.js" />
</Scripts>
</telerik:RadScriptManager>
<script type="text/javascript">
//Put your JavaScript code here.
</script>
<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
</telerik:RadAjaxManager>
<div>
<telerik:RadAjaxPanel runat="server">
<asp:Button ID="Button1" runat="server" Text="Get File Name" OnClick="Button1_Click" />
<asp:Label ID="Label1" runat="server"></asp:Label>
<telerik:RadPdfViewer runat="server" ID="RadPdfViewer1" Height="450px" Width="1000px"
Skin="Default" RenderMode="Lightweight">
<PdfjsProcessingSettings>
</PdfjsProcessingSettings>
</telerik:RadPdfViewer>
</telerik:RadAjaxPanel>
</div>
</form>
</body>
</html>
VB FILE
Imports Telerik.Web.UI
Partial Class _Default
Inherits System.Web.UI.Page
Protected Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Dim filename As String = Server.MapPath("~/prev.pdf")
RadPdfViewer1.PdfjsProcessingSettings.File = filename
Dim currentPage = RadPdfViewer1.ActivePage
Dim result As String = String.Format("Opened file with name: <strong>{0}</strong> on page: <strong>{1}</strong><br />", filename, currentPage)
Label1.Text = result
End Sub
End Class
The result is that issue an error "PDF file fails to process".
How to solve?

Hello Giuseppe,
The path to the PDF file should ve virtual, but not physical. Skipping the Server.MapPath part of the provided snippet will allow you to load the desired file successfully:
Protected Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Dim filename As String = "./Test.pdf"
RadPdfViewer1.PdfjsProcessingSettings.File = filename
Dim currentPage = RadPdfViewer1.ActivePage
Dim result As String = String.Format("Opened file with name: <strong>{0}</strong> on page: <strong>{1}</strong><br />", filename, currentPage)
Label1.Text = result
End Sub
Regards,
Vessy
