  it????????¬???????s just a thought :
  1. set report to double-pass
  2. at first-pass : calculate the height of detail data
  3. at final-pass : page break is done by adjusting header's height
  4. look at my sample (groups.frx & data.xml), i couldnt understand the way fastreport think, why do i need to adjust 18.9F (data1.height) in code :

      private void PageFooter1_BeforePrint(object sender, EventArgs e)
      {
        if (Engine.FinalPass)
          position = 18.9F;
      }
  

  perhaps because record.movenext in data1
  
  5. avoid 'cangrow' property, more headache [img]style_emoticons/<#EMO_DIR#>/rolleyes.gif" style="vertical-align:middle" emoid=":rolleyes:" border="0" alt="rolleyes.gif" /> 6. an alternative: page break is done by engine.startnewpage();[/img]

      private void GroupHeader1_AfterPrint(object sender, EventArgs e)
      {
        if (Engine.FirstPass)
        {
          height = 0;
        }
        else
        { 
          if (position + groupHeight + list[counter] > contentHeight)
            Engine.StartNewPage();
          else                     
            position += groupHeight;
          counter += 1;
        }
      }

  Thank you for your suggestion!
  
  We haven't been able to get your solution to work in our project but we have found another solution that seems to be working:
  

                          CurrentReport.FindObject<DataHeaderBand>("DataUsedHeatTransferCoefficients_Header").BeforePrint += (sender, e) =>
                          {
                              if (!CurrentReport.Engine.FirstPass)
                              {
                                  if (CurrentReport.Engine.FreeSpace < contentHeight + CurrentReport.FindObject<BandBase>("DataUsedHeatTransferCoefficients_Header").Height)
                                      CurrentReport.Engine.StartNewPage();
                              }
                          };
                          CurrentReport.FindObject<DataBand>("DataUsedHeatTransferCoefficients").AfterPrint += (sender, e) =>
                          {
                              if (CurrentReport.Engine.FirstPass)
                                  contentHeight += CurrentReport.FindObject<BandBase>("DataUsedHeatTransferCoefficients").Height;
                          };
  

  
  The snag is that this has to be repeated for each and every table.
