如何设置过滤条件？

[zhangyu_ji]

if sle_date_begin.text<>'' then
ls_search_tj="year=sle_date_begin.text"
if sle_date_end.text<>'' then
ls_search_tj="year>year(sle_date_begin.text) and year<year(sle_date_end.text)"
end if
end if
if sle_id.text<>'' then
ls_search_tj=ls_search_tj+"and teacher_id=sle_id.text"
end if
tab_yewu_search.tabpage_teach.dw_teach_grid.setfilter(ls_search_tj)
tab_yewu_search.tabpage_teach.dw_teach_grid.filter()

楼上的兄弟，错了！
应该依次改为
ls_search_tj="year='"+sle_date_begin.text+"'"
ls_search_tj="year>year("+sle_date_begin.text+") and year<year("+sle_date_end.text+")"
ls_search_tj+"and teacher_id='"+sle_id.text+"'"

year这个字段是字符型的话这一句的类型就不匹配了
ls_search_tj="year>year("+sle_date_begin.text+") and year<year("+sle_date_end.text+")"

最后一句的and前面要加一个空格

谢谢各位高手！！！！！

[你的昵称已存在]

if sle_date_begin.text<>'' then
ls_search_tj="year=sle_date_begin.text"
if sle_date_end.text<>'' then
ls_search_tj="year>year(sle_date_begin.text) and year<year(sle_date_end.text)"
end if
end if
if sle_id.text<>'' then
ls_search_tj=ls_search_tj+"and teacher_id=sle_id.text"
end if
tab_yewu_search.tabpage_teach.dw_teach_grid.setfilter(ls_search_tj)
tab_yewu_search.tabpage_teach.dw_teach_grid.filter()
是你定义的有错误ls_search_tj="year=sle_date_begin.text"
在这一行中在执行时把sle_date_begin.text当成字符串了应该这样:
ls_search_tj="year="+'"'sle_date_begin.text+'"'
还有几个是一样的，你试下吧
