前台代码格式：

<TemplateField ...>    <ItemTemplate>       <asp:TextBox .../>    </ItemTemplate></TemplateField>

例子:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head runat="server">    <title></title></head><body>    <form id="form1" runat="server">    <asp:SqlDataSource ID="SqlDataSource1" runat="server"         ConnectionString="<%$ ConnectionStrings:AdventureWorksConnectionString %>"         SelectCommand="SELECT Person.Contact.FirstName, Person.Contact.LastName         FROM Person.Contact         INNER JOIN HumanResources.Employee ON Person.Contact.ContactID = HumanResources.Employee.ContactID         WHERE (Person.Contact.LastName LIKE N'A%')         ORDER BY Person.Contact.LastName, Person.Contact.FirstName">    </asp:SqlDataSource>    <asp:Repeater ID="Repeater1" runat="server" DataSourceID="SqlDataSource1"><%--        <ItemTemplate>            <asp:Label runat="server" ID="lblLast">Name:&nbsp;</asp:Label>            <asp:Label runat="server" ID="lblName" Text='<%# DataBinder.Eval(Container.DataItem, "LastName")+", "+DataBinder.Eval(Container.DataItem, "FirstName") %>' />        </ItemTemplate>--%>        <SeparatorTemplate>            <hr />        </SeparatorTemplate>    </asp:Repeater>    </form></body></html>

后台代码:

using System;using System.Web.UI;using System.Web.UI.WebControls;public partial class _Default : Page{    protected override void OnInit(EventArgs e)    {        base.OnInit(e);        Repeater1.ItemTemplate = new TheItemTemplate();    }    protected void Page_Load(object sender, EventArgs e)    {        DataBind();    }}public class TheItemTemplate : ITemplate{    #region Implementation of ITemplate    public void InstantiateIn(Control container)    {        var lblLast = new Label {ID = "lblLast", Text = "Name: "};        container.Controls.Add(lblLast);        var lblName = new Label {ID = "lblName"};

//这里是用于绑定数据        lblName.DataBinding += delegate(object sender, EventArgs e)                               {                                   var theLabel = (Label) sender;                                   var dataItem = DataBinder.GetDataItem(theLabel.BindingContainer);                                   theLabel.Text = DataBinder.Eval(dataItem, "LastName") + ", " +                                                   DataBinder.Eval(dataItem, "FirstName");                               };        container.Controls.Add(lblName);    }    #endregion}
