    I'm currently trialling Reporting, and am a little confused as to how to export a report with data from C#.

    I am using the standalone report designer to save a trdx file using the ObjectDataSource and I'm trying to export to PDF, looking at the KB I have the following code block:

    Order tempOrder = new Order("12345", "Mr Test");
                Telerik.Reporting.Report report = new Telerik.Reporting.Report();
                report.DataSource = tempOrder;
                System.Collections.Hashtable deviceInfo = new System.Collections.Hashtable();
                UriReportSource reportSource = new UriReportSource();
                reportSource.Uri = @"E:\Program Files (x86)\Telerik\Reporting Q2 2014\Report Designer\Examples\Order.trdx";
                Telerik.Reporting.Processing.ReportProcessor reportProcessor = new Telerik.Reporting.Processing.ReportProcessor();
                Telerik.Reporting.Processing.RenderingResult result = reportProcessor.RenderReport("PDF", reportSource, deviceInfo);
                string fileName = result.DocumentName + "." + result.Extension;
                string path = System.IO.Path.GetTempPath();
                string filePath = System.IO.Path.Combine(path, fileName);
                using (System.IO.FileStream fs = new System.IO.FileStream(filePath, System.IO.FileMode.Create))
                    fs.Write(result.DocumentBytes, 0, result.DocumentBytes.Length);

    Which seems to output a pdf using my trxd file however I can find no way to pass in both the data source (or the Report variable with data source defined) and the path to the trdx file.

    Hi Mark,

    If your intend is to use the same data as at designing the report, please check the Deploying trdx (XML report definition) that uses external assembly KB article.

    In case you want to change the data, you will have to deserialize the report into Telerik.Reporting.Report object and set the report's and nested data items' DataSource properties at run-time. An example of such approach is illustrated in the Changing the connection string dynamically according to runtime data KB article.

    I hope the above information is helpful.
