Linq to SQL:如何更新包含多个表数据的FormView?

你需要加入

from c in db.Customer
join a in db.Account
on a.customerID equals c.customerID
select new Model {FirstName = c.firstName,LastName = c.lastName,Address = c.address,AccountRate = a.accountRate}

将您的模型定义为某个类并绑定到该类。

我从不使用Linq to SQL,但在实体框架中,我需要这样做:

protected void ObjectDataSource_Updating(object sender, ObjectDataSourceMethodEventArgs e)
    {
        // Declaring the Entity context 
        AvalonEntities db = new AvalonEntities();

        // In updating méthod of a ObjectDataSource the "e" arg is my customer, so i grab this
        customer cus = (customer)e.InputParameters[0];


        // say that i have a DropDown to select the account ...
        // I Get de DropDown and get your SelectedValue.
        DropDownList ddlAccount  = (DropDownList)FormView1.FindControl("ddlAccount");
        // Whit the value i declare a new account
        account ac = new account () { id_account = int.Parse(ddlAccount.SelectedValue) };
        // and associate it to Customer
        cus.account = ac;

希望能帮上忙

我已经成功地从链接类中检索了一些属性,如下所示:

First Name:
<asp:TextBox ID="FirstNameTextBox" runat="server"
 Text='<%# Bind("Entitycontact.Namefirst") %>' />
