Hi Metin

For some people you have to ask clearly. ;)

Not tested. Had to do something like this recently.

local lnDataRows, lnDisplayRows
store 0 to lnDataRows,lnDisplayrows

select count(*) from (this.recordsource) into array laCount
if _Tally#0
lnDataRows = laCount[1]
endif

lnDisplayRows = (this.height - iif(inlist(this.scrollbars,1,3),sysmetric(8),0) - this.headerheight) / this.rowheight

if lnDataRows > lnDisplayRows
if inlist(this.scrollbars,0,1)
this.scrollbars = this.scrollbars + 2
endif
else
if inlist(this.scrollbars,3,2)
this.scrollbars = this.scrollbars - 2
endif
endif
