GridView的绑定到IList＆LT;＆BusinessObject的GT;包含一个IList＆LT;＆BusinessObject的GT; [英] Binding Gridview to IList<BusinessObject> that contains an IList<BusinessObject>

问题描述

我在遇到麻烦找出如何自定义的IList绑定到一个gridview。 IList中包含其他自定义的IList。我需要从这个IList的一个属性绑定到GridView。

I'm having trouble figuring out how to bind a custom IList to a gridview. The IList contains another custom IList. I need to bind a property from this IList to the gridview.

public class Seminar : BusinessObject
{
    private string _description = String.Empty;
    private List<User> _attendees;

    public string Description {get {return _description;} set {_description = value;}}
    public List<User> Attendees {get {return _attendees;} set {_attendees = value;}}
}

public class User : BusinessObject
{
    private string _name = String.Empty;
    public string Name { get { return _name; } set { _name = value; } }
}

后端page.aspx.cs：

Backend page.aspx.cs:

List<Seminar> seminarList = SeminarManager.Get(id);
gridSeminars.DataSource = seminarList;
gridSeminars.DataBind();

前端pa​​ge.aspx：

Frontend page.aspx:

<asp:GridView ID="gridSeminars" runat="server">
<Columns>
    <asp:BoundField DataField="Id" />
    <asp:BoundField DataField="Description" />
    <asp:BoundField DataField="Name" />
</Columns>
</asp:GridView>

问题是在GridView填充名称字段。所有建议都欢迎。

The problem is with populating the "Name" field in the gridview. All suggestions are welcome.

推荐答案

你有没有试过，

Attendees.Name

编辑：
与会者是一个IEnumerable本身。以上建议仅适用于Attendee.Name

Attendees is an IEnumerable itself. The above suggestion only works with Attendee.Name

如果您wan't显示你需要做一个TemplateField的所有与会者，也许使用一个中继器或东西...是这样的：

If you wan´t to display all the attendees you need to make a templatefield and maybe use a repeater or something...something like:

   <asp:TemplateField>
        <ItemTemplate>
            <asp:Repeater runat="server" DataSource='<%# Eval("Attendees") %>'>
                <ItemTemplate>
                    <tr>
                    <td>
                    Name
                    </td>
                    <td>
                        <%# Eval("Name")%>
                    </td>
                    </tr>
                </ItemTemplate>
            </asp:Repeater>
        </ItemTemplate>
    </asp:TemplateField>
