Repeater嵌套。子控件如何得到父控件中的值

[yzg614]

<asp:Repeater ID="rpCity" runat="server" OnItemDataBound="rpCity_ItemDataBound">
<ItemTemplate>
<div class="box">
<div class="area_01"><%#Eval("city_name")%>"><%#Eval("city_code")%></div>
<div class="c">
<ul>
<asp:Repeater ID="rpTitle" runat="server">
<ItemTemplate>
<li><a href="http://这里如何取rpCity中的city_code" title="<%#Eval("HC_NewTitle")%>" target="_blank">
<div class="txt">
<%#Eval("HC_NewTitle")%>
</div>
</a>
</li>
</ItemTemplate>
</asp:Repeater>
</ul>
</div>
</div>
</ItemTemplate>
</asp:Repeater>
在子rpTitle中如何取父rpCity中的<%#Eval("city_code")%>的值

[笨笨兔兔兔兔兔]

<input id="hd1" type="hidden" runat="server" value='<%# Eval...%>' />

repeater_databind...

(( (e....as row).parent.parent as row).findcontrol as ...).value

rpCity的databind里面绑定rpTitle
像这种潜套数据显示可以这么做
当然了你也可以在rpCity的rowcommand里面
上面的方法是初始化一起就出来了
下面的方法是动态的显示

[Aderlee]

要把<%#Eval("city_code")%>值放在一個控件的Text或其他屬性里獲取，比如
<div class="area_01"> <asp:Label Runat="server" ID="Label1" Text='<%#Eval("city_name")%>'> </asp:Label>
</div>
在後臺你就可以通過findcontrol到那個Label1來得到它的Text了

目前想到的方法，请参考

<asp:Repeater ID="Repeater1" runat="server"> 
     <ItemTemplate> 
        OrderID: <%# Eval("OrderID")%>
        CustomerID : 
         <asp:Label ID="Label1" runat="server" Text='<%#Eval("CustomerID")%>'></asp:Label> <br />
        <asp:Repeater ID="Repeater2" runat="server" DataSource='<%# GetOrderDetails(Convert.ToInt32(Eval("OrderID"))) %>'> 
            <ItemTemplate>  
                  
                子容器得到CustomerID : <%# ((Label)((RepeaterItem)((Repeater)(((RepeaterItem)Container).NamingContainer)).NamingContainer).FindControl("Label1")).Text %> 
                UnitPrice: <%#Eval("UnitPrice")%> <br />
            </ItemTemplate> 
        </asp:Repeater> 
        <br />                 
     </ItemTemplate> 
</asp:Repeater>

private void BindRepeater()
{
    SqlConnection cn = new SqlConnection(@"server=.\SQLExpress;uid=sa;pwd=;database=Northwind");
    SqlDataAdapter da = new SqlDataAdapter("select top 10 orderid, CustomerID, OrderDate from Orders", cn);
    DataSet ds = new DataSet();
    cn.Open();
    da.Fill(ds);
    cn.Close();
    Repeater1.DataSource = ds.Tables[0].DefaultView;
    Repeater1.DataBind();
}

protected DataTable GetOrderDetails(int orderID)
{
    SqlConnection cn = new SqlConnection(@"server=.\SQLExpress;uid=sa;pwd=;database=Northwind");
    SqlDataAdapter da = new SqlDataAdapter("select ProductID, UnitPrice from [Order Details] where orderid = @orderid", cn);
    da.SelectCommand.Parameters.AddWithValue("@orderid", orderID);
    DataSet ds = new DataSet();
    cn.Open();
    da.Fill(ds);
    cn.Close();
    return ds.Tables[0];
}

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

也可以简单一点..

<asp:Repeater ID="Repeater1" runat="server"> 
     <ItemTemplate> 
        OrderID: <%# Eval("OrderID")%>
        CustomerID : 
         <asp:Label ID="Label1" runat="server" Text='<%#Eval("CustomerID")%>'></asp:Label> <br />
        <asp:Repeater ID="Repeater2" runat="server" DataSource='<%# GetOrderDetails(Convert.ToInt32(Eval("OrderID"))) %>'> 
            <ItemTemplate>  
                  
                子容器得到CustomerID : <%# ((Label)((RepeaterItem)(Container.NamingContainer.NamingContainer)).FindControl("Label1")).Text %> 
                UnitPrice: <%#Eval("UnitPrice")%> <br />
            </ItemTemplate> 
        </asp:Repeater> 
        <br />                 
     </ItemTemplate> 
</asp:Repeater>
