推荐答案

亲爱的

如果要从数据库中获取组合的数据，则可以使用联合查询来选择选择组合框"，例如

hi dear

If you are fetching data for combo from database then you can use union query for select "Select combobox" like

select Val,Txt from tblComboMaster
union All
select '0' as Val, 'Select combobox' as Txt
order by Val

绑定组合框中的选定值= 0后，

谢谢

after it bind selected value = 0 from combobox

Thanks
