Solution

You can use the following code snippet to programmatically export the report into PDF format from a Web Site or Web Application project:

void ExportToPDF(Telerik.Reporting.Report reportToExport)
    {
        ReportProcessor reportProcessor = new ReportProcessor();
        Telerik.Reporting.InstanceReportSource instanceReportSource = new Telerik.Reporting.InstanceReportSource();
        instanceReportSource.ReportDocument = reportToExport;
        RenderingResult result = reportProcessor.RenderReport("PDF", instanceReportSource, null);

        string fileName = result.DocumentName + "." + result.Extension;

        Response.Clear();
        Response.ContentType = result.MimeType;
        Response.Cache.SetCacheability(HttpCacheability.Private);
        Response.Expires = -1;
        Response.Buffer = true;

        Response.AddHeader("Content-Disposition",
                           string.Format("{0};FileName=\"{1}\"",
                                         "attachment",
                                         fileName));

        Response.BinaryWrite(result.DocumentBytes);
        Response.End();
    }    

Sub ExportToPDF(ByVal reportToExport As Telerik.Reporting.Report)   

        Dim reportProcessor As New ReportProcessor()
        Dim instanceReportSource As New Telerik.Reporting.InstanceReportSource()
        instanceReportSource.ReportDocument = reportToExport
        Dim result As RenderingResult = reportProcessor.RenderReport("PDF", instanceReportSource, Nothing)

        Dim fileName As String = result.DocumentName + "." + result.Extension 
        Response.Clear()   
        Response.ContentType = result.MimeType   
        Response.Cache.SetCacheability(HttpCacheability.Private)   
        Response.Expires = -1   
        Response.Buffer = True  
        Response.AddHeader("Content-Disposition", String.Format("{0};FileName=""{1}""", "attachment", fileName))   
        Response.BinaryWrite(result.DocumentBytes)   
        Response.End()   
    End Sub
