Question

I have tried to Google my problem, but I have found nothing about my problem.

I would like to rename dynamically my reports from Reporting Services when I export them using the ReportViewer. Basically, the format will be reportName + timestamp.

Is there anyway to do that using C# or Reporting Services itself?

Here’s how I include the reportviewer on my pages:

<rsweb:ReportViewer ID="rv" runat="server" ShowToolBar="true" ShowParameterPrompts="false"
    BackColor="#F0F8FF" Height="1200px" Width="100%" ProcessingMode="Remote" EnableViewState="true"
    Visible="false" SizeToReportContent="True">
    <LocalReport EnableExternalImages="True">
    </LocalReport>
</rsweb:ReportViewer>

I solved the problem using a simple method and I hope to be able to help someone with the code below:

    protected void btnCreate_Click(object sender, System.EventArgs e)
    {
        if (ddlExportFormat.SelectedIndex != 0)
        {
            ExportReport(ddlExportFormat.SelectedValue);
            btnShow_Click(sender, e);
        }
    }

    private void ExportReport(String format)
    {
        // Variables
        Warning[] warnings;
        string[] streamIds;
        string mimeType = string.Empty;
        string encoding = string.Empty;
        string extension = string.Empty;

        string fileName = _reportName +"_"+ DateTime.Now.ToString("yyyyMMdd HH:mm"); 


        // Setup the report viewer object and get the array of bytes
        ReportViewer viewer = new ReportViewer();
        viewer.ProcessingMode = ProcessingMode.Local;

        viewer.ServerReport.ReportServerUrl = new System.Uri(_reportServerUrl);
        viewer.ServerReport.ReportPath = _reportPath;

        if (this.PrepareReportParameters())
        {
            viewer.ServerReport.SetParameters(lstReportParameters);
        }


        byte[] bytes = viewer.ServerReport.Render(format, null, out mimeType, out encoding, out extension, out streamIds, out warnings);


        // Now that you have all the bytes representing the PDF report, buffer it and send it to the client.
        Response.Buffer = true;
        Response.Clear();
        Response.ContentType = mimeType;
        Response.AddHeader("content-disposition", "attachment; filename=" + fileName + "." + extension);
        Response.BinaryWrite(bytes); // create the file
        Response.Flush(); // send it to the client to download
    }
