How to set the number of rows per page dynamically

Question

Hello all,
i urgent need the option to set the number of rows per page dynamically.
I've got a parameter.
In dependence of the value of this paramter i want to set the number of rows per page of a repeating frame.
The Reports Builder version i use is 10.1.2.0.2
I defined a report trigger.
My code so far:
function R_G_BEMERKUNGFormatTrigger return boolean is
begin
if :vYN_Display_one_per_page = 'Y' then
--what i've to write right here??
return (TRUE);
else
     return (TRUE);
end if;
return (TRUE);
end;
Can anyone help me please??
Best regards
Florian

Do you just need to change back and forth between 1 and some other number? If so, you can create two identical layouts, one with the "number of rows per page" preperty (on the repeating frame) set to 1 and the other layout set to whatever. You would have to have duplicate layouts for each group you wanted to do this with. Your format trigger on the outermost master group frame where num of rows was 1 would look like:
function M_G_ename_GRPFRFormatTrigger return boolean is
begin
  if :vYN_Display_one_per_page = 'Y'  then
    return (TRUE);
  else
    return (FALSE);
  end if;
end;Your format trigger on the outermost master group frame where num of rows was whatever would look like:
function M_G_ename_GRPFR1FormatTrigger return boolean is
begin
  if :vYN_Display_one_per_page = 'N'  then
    return (TRUE);
  else
    return (FALSE);
  end if;
  return (TRUE);
end;
