ASP.NET数据绑定的一般情况
1、<%= C#代码 %> //调用代码隐藏页面的方法、属性、或者字段
这里一般是调用属性和方法比较多，要注意调用的属性、方法或者字段的作用域，必须是可以在ASPX页面可以访问到的。
代码示例（ASPX）：<%=Property%>
在（CS）是： public string Property{ get { return "This is a Property";} }
属性是这样使用的，方法和字段的使用类似，也是这样实现的。
2、<%#数据绑定表达式%>//是在列表控件里面使用的
使用方式一：<%# Eval("FirstName")%>
使用方式二：<%# DataBinder.Eval(Container.DataItem, "SecondName")%>
下面附上我调试的源码，可以复制过去看看
在ASPX页面：
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="DataBindEx._Default" %>
<%@ Import Namespace="System.Data" %>
<%@ Import Namespace="System.Collections.Generic" %>

<body>
<form runat="server">

<%=Property%>
<br />
<asp:TextBox ID="TextBox1" Text="This is TextBox of serverClient " runat="server"></asp:TextBox>
<br />
<%=Method()%>
<br />
<br />
<asp:Label ID="Label1" runat="server"><%=TextBox1.Text %></asp:Label>
<br />
<%=(Property + " " + Method())%>
</div>
<div>
<asp:Repeater ID="Repeater1" runat="server" OnItemDataBound="RptAllOnItemDataBound">
<HeaderTemplate>
This is Header<br />
</HeaderTemplate>
<ItemTemplate>
FirstName:<%# Eval("FirstName")%>
SecondName:<%# DataBinder.Eval(Container.DataItem, "SecondName")%>
FullName:<%# (Container.DataItem as DataBindEx.Person).FullName%>
<asp:Literal ID="Others" runat="server"></asp:Literal>
<br />
</ItemTemplate>
<FooterTemplate>
This is footer<br />
</FooterTemplate>
</asp:Repeater>
</div>
</form>
</body>
</html>
