如何用modify动态设置一列为dropdownlistbox风格?
for ll_i = 1 to ll_count
ls_cloumncode = tab_1.tabpage_1.dw_tj.describe("#" + string(ll_i) + ".NAME")
//messagebox("",ls_cloumncode)
if ls_cloumncode = "zfgw" then
//messagebox("","aa")
tab_1.tabpage_1.dw_tj.modify(ls_cloumncode + ".Edit.Style='ddlb'")
tab_1.tabpage_1.dw_tj.modify(ls_cloumncode + ".ddlb.AllowEdit='yes'")
tab_1.tabpage_1.dw_tj.modify(ls_cloumncode + ".values='男~tA/女~tB'")
end if
