thank you for your help, it worked! Here is the sample code that I used.

case .cboselopt = 6 &&= "Order Date"
lc_fromdate = .txtfdate.value
.grdcrd.recordsource = 'lv_offopt7'
requery('lv_offopt7')
.hldcount = reccount('lv_offopt7')
.rec_view

method rec_view
if .hldcount > 0
thisform.cmdview.visible = .t.
else
thisform.cmdview.visible = .f.
endif

propery
hldcount
