repeater嵌套问题

ly015 2010-11-18 02:50:42

<asp:Repeater ID="Repeater1" runat="server" OnItemDataBound="Repeater1_ItemDataBound">
<HeaderTemplate>
<asp:Repeater ID="Repeater2" runat="server">
<ItemTemplate>
<asp:Label ID="Label2" runat="server" Text='<%#Eval("pc_name") %>'
></asp:Label>
</ItemTemplate>
</asp:Repeater>
</HeaderTemplate>
<ItemTemplate>
<li><span><%#Container.ItemIndex+2 %></span><div class="p-name"><a href='../product.aspx?id=<%#Eval("pc_id") %>'><%#Eval("pc_name") %>
</a></div></li>
</ItemTemplate>
</asp:Repeater>

在这个HeaderTemplate 里Repeater2 的值怎么取到 Repeater1 绑定的值

我在Repeater1_ItemDataBound里写了

if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
string au_id = ((DataRowView)e.Item.DataItem).Row["pc_id"].ToString();
Repeater repeaterSub = (Repeater)e.Item.FindControl("Repeater2");
if (repeaterSub != null)
{
OleDbConnection cn = new OleDbConnection(db.connstring);
OleDbCommand cmd = new OleDbCommand("select * from product where (id = ?)", cn);
cmd.Parameters.Add("user_name", OleDbType.Integer);
cmd.Parameters["pc_id"].Value =au_id;
cn.Open();
repeaterSub.DataSource = cmd.ExecuteReader();
repeaterSub.DataBind();
cn.Close();
}

}

没反应请问怎么弄

你是在headeritem里面绑定的子repeater在绑定事件中
你的条件却是if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)当然没有反映了。
改成
if (e.Item.ItemType == ListItemType.Header)

你在绑定第一个Repeater时return DataSet或DataTable看下。。。。

在if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
这加个断点调试下
