Dim cxlb As WinForm.ComboBox = e.Form.Controls("查询类别")
Dim cxcf As WinForm.ComboBox = e.Form.Controls("查询成份")
Dim cxmc As WinForm.ComboBox = e.Form.Controls("查询名称")
cxmc.ComboList = DataTables("面料信息表").GetComboListString("面料名称","面料类别 = '"& cxlb.text &"'" And "成份 = '"& cxcf.text &"'" )
这句代码哪里错了,通过“面料信息表”的“面料类别”和“成份”查询面料名称
