数据绑定的问题~麻烦大家帮我看看，谢了！！
我用一个CheckBoxList控件绑定数据，不知道为什么什么都不显示，调试无错误提示，代码也没发现什么错误，麻烦大家帮我看看是什么原因，小弟先谢了。代码如下：
public class WebForm1 : System.Web.UI.Page
{
protected System.Web.UI.WebControls.CheckBoxList chkTitles;
protected System.Web.UI.WebControls.Button Button1;
private void Page_Load(object sender, System.EventArgs e)
{
// 在此处放置用户代码以初始化页面
if(!IsPostBack)
{
SqlConnection conPubs;
SqlCommand cmdSelect;
SqlDataReader dtrTitles;
conPubs = new SqlConnection( @"Server=LCH;uid=sa;pwd=123;Database=Pubs" );
cmdSelect = new SqlCommand( "Select Title From Titles", conPubs );
conPubs.Open();
dtrTitles = cmdSelect.ExecuteReader();
chkTitles.DataSource = dtrTitles;
chkTitles.DataTextField = "Title";
chkTitles.DataBind();
dtrTitles.Close();
conPubs.Close();
}
}

1. 确认 Page_Load 执行了
private void Page_Load(object sender, System.EventArgs e)
{
if(!IsPostBack)
{
Response.Write("Page_Load 执行了<BR>");
.....
}
}
2. 确认
Select Title From Titles
有记录返回
3. 在浏览器端查看一下HTML源码Top

思归大哥，我还是找不出什么原因啊，没道理啊。我用别的控件绑定就能显示。我在浏览器查看HTML源码如下：
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" >
<HTML>
<HEAD>
<title>WebForm1</title>
<meta content="Microsoft Visual Studio .NET 7.1" name="GENERATOR">
<meta content="C#" name="CODE_LANGUAGE">
<meta content="JavaScript" name="vs_defaultClientScript">
<meta content="http://schemas.microsoft.com/intellisense/ie5" name="vs_targetSchema">
</HEAD>
<body>
<form name="Form1" method="post" action="WebForm1.aspx" id="Form1">
<input type="hidden" name="__VIEWSTATE" value="dDwtMjAwODM4NTM0Njs7bDxjaGtUaXRsZXM6MDs+PtyU7prrxkSPVTTx++UayUxUfHq2" />
<P><FONT face="宋体"></FONT></P>
<P> </P>
<P>
<table id="chkTitles" border="0">
</table></P>
<P> </P>
<P><FONT face="宋体">
<input type="submit" name="Button1" value="Button" id="Button1" /></FONT></P>
</form>
</body>
</HTML>

check if Page_Load is executed or not, check you have
<%@ Page AutoEventWireup="true" %> in your aspx or you have
this.Load += new EventHandler(Page_Load);
in your codebehindTop
