ASP.NET中多重Repeater使用方法
前台页面部分：
&asp:Repeater id="rptCategories" runat="server"&
&HeaderTemplate&
&table width="100%" border="0" cellspacing="0" cellpadding="0"&
&/HeaderTemplate&
&ItemTemplate&
&!--分类名称--&
&tr&&th&&%# DataBinder.Eval(Container.DataItem, "TypeName")
%&&/th&&/tr&
&!--分类下的产品--&
&asp:Repeater id="rptProduct" runat="server"&
&ItemTemplate&
&tr&&td&&a href='ProductInfo.aspx?Id=&%#
DataBinder.Eval(Container.DataItem, "ID") %&'&&%#
DataBinder.Eval(Container.DataItem, "ProductName")
%&&/a&&/td&&/tr&
&/ItemTemplate&
&/asp:Repeater&
&/ItemTemplate&
&FooterTemplate&
&/FooterTemplate&
&/asp:Repeater&
后台代码部分（部分代码）：
//在绑定分类品名时,绑定分类下的产品
private void rptCategories_ItemDataBound(object sender,
System.Web.UI.WebControls.RepeaterItemEventArgs e)
BLL.Products products =new BLL.Products();
if (e.Item.ItemType == ListItemType.Item ||&&& e.Item.ItemType ==
ListItemType.AlternatingItem)
Repeater rptProduct = (Repeater) e.Item.FindControl("rptProduct");
//找到分类Repeater关联的数据项
DataRowView rowv = (DataRowView)e.Item.DataI
//提取分类ID
int CategorieId = Convert.ToInt32(rowv["ID"]);
//根据分类ID查询该分类下的产品，并绑定产品Repeater
rptProduct.DataSource = products.GetProductsByCategorieId(CategorieId);
rptProduct.DataBind();
另一种方法：
&!-- start parent repeater --&
&asp:repeater id="parentRepeater" runat="server"&
&itemtemplate&
&b&&%# DataBinder.Eval(Container.DataItem,"au_id")
%&&/b&&br&
&!-- start child repeater --&
&asp:repeater id="childRepeater" datasource='&%#
((DataRowView)Container.DataItem)
.Row.GetChildRows("myrelation") %&' runat="server"&
&itemtemplate&
&%# DataBinder.Eval(Container.DataItem,
"[\"title_id\"]")%&&br&
&/itemtemplate&
&/asp:repeater&
&!-- end child repeater --&
&/itemtemplate&
&/asp:repeater&
&!-- end parent repeater --&
后台：public partial class NestedRepeater : System.Web.UI.Page
protected System.Web.UI.WebControls.Repeater
childR//parentR
public NestedRepeater()
Page.Init += new System.EventHandler(Page_Init);
public void Page_Load(object sender, EventArgs e)
//Create the connection and DataAdapter for the Authors table.
SqlConnection cnn = new SqlConnection("server=.;database= user
id=pwd=;");
SqlDataAdapter cmd1 = new SqlDataAdapter("select * from authors", cnn);
//Create and fill the DataSet.
DataSet ds = new DataSet();
cmd1.Fill(ds, "authors");
//Create a second DataAdapter for the Titles table.
SqlDataAdapter cmd2 = new SqlDataAdapter("select * from titleauthor",
cmd2.Fill(ds, "titles");
//Create the relation bewtween the Authors and Titles tables.
ds.Relations.Add("myrelation",
ds.Tables["authors"].Columns["au_id"],
ds.Tables["titles"].Columns["au_id"]);
//Bind the Authors table to the parent Repeater control, and call
parentRepeater.DataSource = ds.Tables["authors"];
Page.DataBind();
//Close the connection.
cnn.Close();
private void Page_Init(object sender, EventArgs e)
InitializeComponent();
private void InitializeComponent()
this.Load += new System.EventHandler(this.Page_Load);
