Device information settings in SSRS are used to pass parameters to a rendering extension. For more information regarding device information settings in reporting services, see Passing Device Information Settings to Rendering Extensions.

For SQL Reporting, none of the options specified in the above article are feasible. We see a lot of scenarios where we would want to modify these settings, and render/export the report in the format that we are looking for.

For SQL Reporting reports, we can explore the SOAP APIs in modifying these device information settings at the run time. If we have integrated SQL Reporting within our applications, this approach is really easy, by just creating a separate function.

Here are some steps to achieve this:

  1. Generate the proxy class for ReportExecution2005.asmx.
  2. Now you have the file named: ReportExecutionService.cs. Add the file to your Windows Azure Project. You can use a function similar to the one provided below: 
    public void Render_Export()
            {
                ReportExecutionService rs = new ReportExecutionService();
                rs.Url = String.Format("https://{0}:443/ReportServer/reportExecution2005.asmx", ConfigurationManager.AppSettings["SERVER_NAME"]);
                rs.CookieContainer = new CookieContainer();
                rs.LogonUser(ConfigurationManager.AppSettings["USERNAME"], ConfigurationManager.AppSettings["PASSWORD"], ConfigurationManager.AppSettings["SERVER_NAME"]);
                
                byte[] result = null;
                string reportPath = "/SSRSReport/Report5";
                string format = "CSV";
                string historyID = null;
     
                // Setting the deviceinfo parameters
                string devInfo = @"<DeviceInfo><FieldDelimiter>;</FieldDelimiter></DeviceInfo>";
                
                string encoding;
                string mimeType;
                string extension;
                Warning[] warnings = null;
                string[] streamIDs = null;
     
                ExecutionInfo execInfo = new ExecutionInfo();
                ExecutionHeader execHeader = new ExecutionHeader();
     
                rs.ExecutionHeaderValue = execHeader;
                execInfo = rs.LoadReport(reportPath, historyID);
                String SessionId = rs.ExecutionHeaderValue.ExecutionID;
                
                // code snippet to set the DataSource credentials.
                if (execInfo.CredentialsRequired)
                {
                    List<DataSourceCredentials> credentials = new List<DataSourceCredentials>();
                    foreach (DataSourcePrompt dsp in execInfo.DataSourcePrompts)
                    {
                        DataSourceCredentials cred = new DataSourceCredentials();
                        cred.DataSourceName = dsp.Name;
                        cred.UserName = ConfigurationManager.AppSettings["USERNAME"];
                        cred.Password = ConfigurationManager.AppSettings["PASSWORD"];
                        credentials.Add(cred);
                    }
     
                    Console.WriteLine("Setting data source credentials...");
                    execInfo = rs.SetExecutionCredentials(credentials.ToArray());
                }
     
                // Code snippet to render the file to a specified format.
                try
                {
                    result = rs.Render(format, devInfo, out extension, out encoding, out mimeType, out warnings, out streamIDs);
                    execInfo = rs.GetExecutionInfo();
                }
                catch (Exception ex)
                {
                    throw ex;
                }
     
                // Code snippet to write the file to a specific location using FileStream object
                try
                {
                    FileStream stream = File.Create(@"D:\report.csv", result.Length);                
                    Console.WriteLine("File created.");
                    stream.Write(result, 0, result.Length);
                    Console.WriteLine("Result written to the file.");
                    stream.Close();
                }
                catch (Exception ex)
                {
                    Console.WriteLine(ex.Message);
                }
            }
  3. You can use a config file to store the Username, Password and SQL Reporting server name. The config file will have information as specified below:
    <appSettings>
      <add key="SERVER_NAME" value="SQLReportingServer.reporting.windows.net"/>
      <add key="USERNAME" value="UserName"/>
      <add key="PASSWORD" value="Password"/>    
    </appSettings>
  4. Modify the values as per your SQL Reporting server details.
  5. You might need to extend the default Reporting Services proxy class to enable cookie management, because SQL Reporting uses forms authentication.
