Repeater 嵌套问题，急！

[xyb921]

我想在一个repeater中嵌套另外一个repeater。想给里层的repeater绑定数据源，却无法引用该对象。请高手指教！

请参考
//aspx
<asp:repeater id="repeaterMain" Runat="server" OnItemDataBound="repeaterMain_ItemDataBound">
<ItemTemplate>
<a href='<%#"Details.aspx?au_id=" + DataBinder.Eval(Container,"DataItem.au_id")%>'><%#DataBinder.Eval(Container,"DataItem.au_id")%></a>
<asp:repeater ID="repeaterSub" Runat="server">
<ItemTemplate>
<a href='<%#"Details.aspx?title_id=" + DataBinder.Eval(Container,"DataItem.title_id")%>'><%#DataBinder.Eval(Container, "DataItem.title_id")%></a>
</ItemTemplate>
</asp:repeater>
</ItemTemplate>
</asp:repeater>

//aspx.cs
private void BindMain()
{
SqlConnection cn = new SqlConnection(@"server=.\SQLExpress;uid=sa;pwd=password;database=pubs");
SqlDataAdapter da = new SqlDataAdapter("select au_id from authors", cn);
DataSet ds = new DataSet();
cn.Open();
da.Fill(ds);
repeaterMain.DataSource = ds.Tables[0].DefaultView;
repeaterMain.DataBind();
cn.Close();
}

protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
BindMain();
}
}

protected void repeaterMain_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
string au_id = ((DataRowView)e.Item.DataItem).Row["au_id"].ToString();
Repeater repeaterSub = (Repeater)e.Item.FindControl("repeaterSub");
if (repeaterSub != null)
{
SqlConnection cn = new SqlConnection(@"server=.\SQLExpress;uid=sa;pwd=password;database=pubs");
SqlCommand cmd = new SqlCommand("select title_id from titleauthor where au_id = @au_id", cn);
cmd.Parameters.Add("@au_id", SqlDbType.VarChar, 11).Value = au_id;
cn.Open();
repeaterSub.DataSource = cmd.ExecuteReader();
repeaterSub.DataBind();
cn.Close();
}
}
}
