asp.net dropdownlist和checkboxlist问题 [英] asp.net dropdownlist and checkboxlist problem

问题描述

亲爱的所有人，

我在dropdownlist和复选框控件方面遇到问题.

在我的应用程序中，我有一个Dropdownlist1，我手动填充了五个项目，例如:...

----选择----
NationalSalesManager值= 1
区域经理值= 2
DepotManager值= 3
AreaManager值= 4
主管值= 5
推销员价值= 6

我想在数据库中的dropdownlist选定事件上填充一个复选框列表-Dropdownlist1_SelectedIndexChanged.

当我选择NationalSalesManager时，国民销售经理表的记录显示在checkBoxlist中，当我从下拉列表中选择RegionalManager时，RegionManager表的记录显示在checkBoxList中，与其他情况相同.


请帮助我.
