repeater嵌套

例子一：

.aspx

<asp:repeater id="repeaterMain" Runat="server" OnItemDataBound="repeaterMain_ItemDataBound">
        <ItemTemplate>
        <table>
        <tr><td>
        <a href= " <%#"Details.aspx?au_id=" + DataBinder.Eval(Container,"DataItem.au_id")%> "> <%#DataBinder.Eval(Container,"DataItem.au_id")%> </a> 大類<br>
        </td>
        </tr>
            <asp:repeater ID="repeaterSub" Runat="server">
            <ItemTemplate>
              <tr>
              <td>
              <a href= " <%#"Details.aspx?title_id=" + DataBinder.Eval(Container,"DataItem.title_id")%> "> <%#DataBinder.Eval(Container, "DataItem.title_id")%> </a> 小類
              </td>
              </tr>
            </ItemTemplate>
            </asp:repeater>
        </table>
        </ItemTemplate>
       
        </asp:repeater>

.cs

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

    private void BindMain()
    {
        SqlConnection cn = new SqlConnection(@"server=(local);uid=sa;pwd=1234567890;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 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=(local);uid=sa;pwd=1234567890;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();
            }
        }
    }
