  Try this instead RegisterData:
  

  string DataSourceName = "your_datasource_name";
  string SQLQuery = "Your new SQL Query";
  
  TableDataSource table = (TableDataSource)report.GetDataSource(DataSourceName);
  table.SelectCommand = SQLQuery;
  

  
  You can get the query used to design the report and change the sql query.

  I'm not happy wiht this solution, because other class is responsible to create the sql command.
  There are other topic with the same problem without answer. The fast report staff don't look to the forum?

  Have you tried to remove your data source from report, and add the new after?
  
  I think the staff doesn't see this forum...

  I know this is hack but you can remove the data sources from the report, in the designer, once you have finished creating it. That way it can't make any database calls you added for testing. As long as the data is registered with the correct name the report engine will still work correctly.
  
  If you have relations in the report you would need to open the report in a text editor and manually remove the connections leaving the relations intact.
  
  There is a way to edit the report file source to leave the DataSources usable in the Editor without the actual database connection being present. I can try to elaborate if interested. Keep in mind it falls under the hack category as well.

  Do not use report designer to create datasource.
  
  All you have to do :
  
  1. You have blank frx file as a template, open designer.exe , save as blank_report.frx
  
  2. Create a code in .net application
  

  using (OleDbConnection cnn = new OleDbConnection(@"........"))
  {
      cnn.Open();
  
      using (OleDbCommand cmd = new OleDbCommand())
      {
          cmd.Connection = cnn;
          cmd.CommandType = CommandType.Text;
          cmd.CommandText = "..........";
  
          using (OleDbDataReader dr = cmd.ExecuteReader())
          {
              using (DataTable dt = new DataTable())
              {
                  dt.Load(dr);
                  dt.TableName = "MainReport";
  
                  FastReport.Report report = new FastReport.Report();
                  report.Load("blank_report.frx")
                  report.RegisterData(dt, dt.TableName);
  
                  //YOU CAN REMOVE AFTER FINISH WITH THE DESIGNER
                  //IN DESIGNER WINDOW, YOU CAN PREVIEW THE REPORT BECAUSE
                  //DATA FROM DATABASE IS REGISTERED
                  report.GetDataSource(dt.TableName).Enabled = true;
                  FastReport.DataBand dataBand = (FastReport.DataBand)report.FindObject("Data1");
                  dataBand.DataSource = report.GetDataSource(dt.TableName);
                  report.Design(true);
  
  
                  //UNCOMMENT AFTER FINISH WITH THE DESIGNER
                  //report.FileName = "My Report";
                  //report.Prepare();
                  //PreviewControl1.AddTab(report, report.FileName);
                  //PreviewControl1.ZoomPageWidth();
              }
          }
      }
  }
  

  
  3. After finish with report designer, save the frx file
  4. Comment / Uncomment code above
