我有两个表:ServiceType
和ServiceTerm
。
这些表格彼此相辅相成,并合并到关联表ServiceRate中。一个ServiceType
可以有多个ServiceTerms
,但并不总是全部。{/ p>
在我的asp.net表单(VB)上,我想将其编码到哪里,我可以使用复选框将每行添加到数据库,以选择适用于所选的ServiceTerms
ServiceType
。
我是asp.net的新手,也是SQL Server 2008的新手。

以下是我在其中一个项目中完成的示例: 其中chSportsList是Id的复选框列表
List<ListItem> list_chSportsList = new List<ListItem>();
foreach (ListItem chsli in chSportsList.Items)
{
Guid gui2 = Guid.Parse("00000000-0000-0000-0000-000000000000");
try
{
gui2 = Guid.Parse(chsli.Value.ToString());
}
catch { Response.Redirect("default.aspx"); }
db = new IRANSportEntities();
Customer_Sports customer_Sport = new Customer_Sports();
customer_Sport = db.Customer_Sports.FirstOrDefault(x => x.Id_Customer == gui1 && x.Id_Sports == gui2);
if (customer_Sport == null)
{
if (chsli.Selected == true)
{
db = new IRANSportEntities();
Customer_Sports _save = new Customer_Sports() { Id = Guid.NewGuid(), Id_Customer = gui1, Id_Sports = gui2 };
db.Customer_Sports.AddObject(_save);
db.SaveChanges();
}
}
else
{
if (chsli.Selected == false)
{
db.Customer_Sports.DeleteObject(customer_Sport);
db.SaveChanges();
}
}
}
