  set the TfrxDBDataset.RangeBegine = rbCurrent and RangeEnd=reCurrent in the detail TfrxDBDataSet.

  Well, I can't do that because I have a single datasource for all the bands, so for some bands I want to display the first record, for others I want to display all records...

  I've added this possibility to 3.03.

  Setting the property RowCount = 1 to a band displays the first record only which is OK but in this case the FR enters an infinite loop which creates a huge number of pages (every band gets displayed again and again, I have stopped it after 1500 pages...).
  
  If you set RowCount = 2 for example everything works fine.
  I have tested this under C++Builder 6. The dataset has 3 records, all bands have the same dataset.
  
  Thanks,

  It works fine for me at least on demo reports.

  OK, I have tested the demo reports and it seems to work fine.
  
  But I'm using C++Builder 6 and it doesn't work properly...maybe the BCB is the cause?
  
  You can reproduce this easily:
  
  1. Open C++Builder 6
  2. Drop a FastReport and a BDE table linked to DBDEMOS->Biolife table onto the main form
  3. Drop a TFrxdataset component
  4. Link BDETable to TFrxdataset
  5. Link TFrxdataset to FastReport
  5. Make BDETable active
  6. Design report
  7. Goto Report->Data... menu and select frxDBDataset1
  8. Drop a MasterData band onto the report and assign frxDBDataset1 as datasource
  9. Drop a couple of fields onto the band
  10. Set the property RowCount = 1 for the MasterData band
  11. Preview the report
  
  You sould see lots of pages that are being produced.

  You shouldn't link a dataset to the TfrxReport.DataSet!

  OK, I have tried again:
  
  In C++Builder 6:
  
  It works fine if you have only one detail band, but if you place onto the report 2 Detail bands linked to the same datasource, and set RowCount = 1 for both it won't work (it will produce lots of pages).
  
  In Delphi 7: It works perfectly !
  
  So, the C++Builder 6 version of FR3 seems to have some problems...
