repeater嵌套c#中Repeater怎么嵌套Repeater？

如何进行Repeater嵌套Repeater

假设存在“大商品”、“小商品”和“货物”两张表，小商品的BID是大商品的外键；货物的GID又是小商品的外键。

那么：

<asp:Repeater id="repBigGoods" DataKeys="xxx"....>

<ItemTemplate>

<%#Eval("BigCategoryName")%>

<asp:Repeater id="repSmallgoods" ... DataSourceId="dsSmallGoods" DataKeys="xxx">

<ItemTemplate> <%#Eval("SmallCategoryName")%>

<asp:Repeater id="repGoods" ...>

<ItemTemplate> <%#Eval("GoodsName")%> </ItemTemplate> </asp:Repeater>

<asp:SqlDataSource id="dsGoods" .... SelectCommand="select GoodsName from goods where gid=@gid"....> <SelectParameter> <asp:Parameter Name="gid" Type="Int32"..../> </SelectParameter> </ItemTemplate>

</asp:Repeater>

<asp:SqlDataSource id="dsSmallGoods" .... SelectCommand="select SmallCategoryName from smalllcategory where bid=@bid"....> <SelectParameter> <asp:Parameter Name="bid" Type="Int32"..../> </SelectParameter>

<ItemTemplate>

</asp:Repeater>

然后：

private void repBigGoods_ItemDataBound(object sender, System.Web.UI.WebControls.RepeaterItemEventArgs e) { RepeaterItem item = e.Item; if( (item.ItemType == ListItemType.Item) || (item.ItemType == ListItemType.AlternatingItem) ) { Repeater repsmallgoods = (Repeater) item.FindControl("repSmallgoods"); SqlDataSource dsSmallGoods = (SqlDataSource)repsmallgoods.FindControl("dsSmallGoods")as SqlDataSource; dsSmallGoods.SelectParameters["bid"].DefaultValue = (e.Item As DataRowView).Row["Primary Column Name"].ToString(); } }

private void repSmallgoods_ItemDataBound(object sender, System.Web.UI.WebControls.RepeaterItemEventArgs e) { RepeaterItem item = e.Item; if( (item.ItemType == ListItemType.Item) || (item.ItemType == ListItemType.AlternatingItem) ) { Repeater repGoods = (Repeater) repsmallgoods.FindControl("repGoods"); SqlDataSource dsGoods = (SqlDataSource)repsmallgoods.FindControl("dsgoods")as SqlDataSource; dsGoods.SelectParameters["gid"].DefaultValue = (e.Item As DataRowView).Row["Primary Column Name"].ToString(); } }

具体可以参考这里（双层嵌套）：

/KB//AspNetNestedRepeaters.aspx

现在有两个repeater控件，分别是repeater1和repeater2，repeater2是嵌套在repeater1的。

获得当前repeater2的ID，然后遍历repeater1中的每一行，如果id一样，那就是哪行了。

这是我想到的最简单的办法，你试试。

也许还能利用datakeys。
