推荐答案

以下链接应为您提供一些想法.
从asp.net中的数据库填充下拉列表 [ ^ ]
从数据库填充下拉列表 [ ^ ]

The below links should give you some idea.
Populate Dropdownlist from Database in asp.net[^]
populate a Dropdown list from database[^]

无法执行此操作.您可以选择以下选项.
从数据库中检索时，将两个列值选择/合并为单个，并以特殊字符分隔，然后将该列值作为下拉列表中的value字段.

例如

从表中选择(作业代码+'';''+项目代码)作为代码，项目.

设置valueField ="Code'';
设置textfield =``Item'';

在撤消下拉选择的值时，只需用'';''分割即可.

问候

There is no way to do this.. you can have following option.
select / merge two column values into a single with separating with special character while retriving from database and then assing that column value as value field in dropdown.

e.g.

select (Job Code + '';'' + Item Code) as Code,Item from Table.

set valueField=''Code'';
set textfield = ''Item'';

while retring dropdown selected value, just split with '';''.
