ListView representation of List<string> inside a gridview

I have a listview inside a templatefield in an asp.net web application.

I need it to display the contents of a collection, 1 per row.

How can I do that?

Current Design:

I want the the table of the ListView to have multiple rows. 1 for each item in the list. So for example:

Breeding Group | Breeding Group Role | Default

     AAA              1111                F
     BBB              2222                T
     CCC              3333                F

And that is for each 'Crop'

Is that possible?

Current Code:

Class:

[Serializable()]
public class UserCrops
{
    public UserCrops(string _Crop, List<string> _BG, List<string> _BGR, List<bool> _Default)
    {
        Crop = _Crop;
        BG = _BG;
        BGR = _BGR;
        Default = _Default;
    }
    public string Crop { get; set; }
    public List<string> BG { get; set; }
    public List<string> BGR { get; set; }
    public List<bool> Default { get; set; }
}

Binding:

    protected void GVUserCrops_RowDataBound(object sender, GridViewRowEventArgs e)
    {

        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            ListView lv = (ListView)e.Row.FindControl("lvBGs");
            lv.DataSource = finalSelection;
            lv.DataBind();
        }
    }

GridView:

    <asp:GridView ID="GVUserCrops" runat="server" AutoGenerateColumns="False" CellPadding="4"
        ForeColor="#333333" GridLines="None" OnRowDataBound="GVUserCrops_RowDataBound"
        Width="634px">
        <AlternatingRowStyle BackColor="White" ForeColor="#284775" />
        <Columns>
            <asp:BoundField DataField="Crop" HeaderText="Crop" />
            <asp:TemplateField HeaderText="BG/BGR">
                <ItemTemplate>
                    <asp:ListView ID="lvBGs" runat="server">
                        <LayoutTemplate>
                            <table style="border: solid 2px #336699;" cellspacing="0" cellpadding="3" rules="all">
                                <tr style="background-color: #336699; color: White;">
                                    <th>
                                        Breeding Group
                                    </th>
                                    <th>
                                        Breeding Group Role
                                    </th>
                                    <th>
                                        Default
                                    </th>
                                </tr>
                                <tbody>
                                    <asp:PlaceHolder ID="itemPlaceHolder" runat="server" />
                                </tbody>
                            </table>
                        </LayoutTemplate>
                        <ItemTemplate>
                            <tr>
                                <td>
                                    <%# Eval("BG")%>

                                </td>
                                <td>
                                    <%# Eval("Default")%>
                                </td>
                            </tr>
                        </ItemTemplate>
                        <AlternatingItemTemplate>
                            <tr style="background-color: #dadada;">
                                <td>
                                    <%# Eval("BG")%>
                                </td>

    </asp:GridView>

Edit:

Screenshot for list: enter image description here

Edit2:

Sketch for what I am trying to accomplish. enter image description here enter image description here

Please excuse the crude drawings. I am trying to get the list called finalSelection(in Sketch#1, 8 items) to appear like the Gridview in Sketch#2. Could probably do it much easier using cell spanning but seems like cheating. So I made a gridview with 1 bound column 'Crop' and another column (templatecolumn) I then put a listview control with a layout like a table(which i love) Problem is when i assign listview.datasource to the finalSelection List is won't show like I am hoping (which seems logical) What can i do to accomplish my goal? :)

Replace the <%# Eval("BG")%> with <%# Container.DataItem %>

EDIT: After screen shot from OP.

Seems your DataSource is wrong. You are referring the class that the list is contained in.

Try this:

lv.DataSource = finalSelection.BG;
