datalist ItemDataBound绑定数据后没有值，急急，，谢谢帮忙！
private string TestPaperID= "tiku3 ";//试卷号
//private string TestPaperName;//试卷号
private int RecorderCount=0;//总记录数
private int pageID=1;//当前页号
private int PageSize=10;//每页记录数
private int pageCount=20;//返回总记录数
private int TotalPageCount=3;//返回总页数


Title title = new Title();
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{


Bind();

//string option;
//option=


}
}


private void Bind()
{

//int id = 4;

title.BindTitleList(DataList1, TestPaperID,RecorderCount, pageID, PageSize, pageCount, TotalPageCount);

// 去数据库取该页对应的数据
//循环该数据集，对每行（每道题），取提号，提干，OPTION
//提号，提干“直接”显示在页面上，OPTION用SPLIT截取
//循环OPTION数组，将每个OPTION加载到RADIO
}
protected void DataList1_ItemDataBound(object sender, DataListItemEventArgs e)
{
//if (e.Item.ItemType == ListItemType.AlternatingItem || e.Item.ItemType == ListItemType.Item)
//{

//RadioButtonList rbl = e.Item.FindControl( "rblTitle ");

Literal ll = (Literal)e.Item.FindControl( "llHtml ");

Label lblid = (Label)e.Item.FindControl( "lblTitleId ");
Label lbl=(Label)e.Item.FindControl( "lbloption ");

//string option;
//option = lbl.Text;

string[] s = lbl.Text.Split( '| ');

string ii = lblid.Text;

string html = " ";
string[] zz = new string[] { " ", "A ", "B ", "C ", "D ", "E ", "F ", "G ", "H " };
for (int i = 1; i <= s.Length; i++)
{
html += " <INPUT type=\ "radio\ " value=\ "1\ " name=\ "sele " + lblid.Text + "\ " ID=\ "Radio " + lblid.Text + "_ " + zz[i].ToLower() + "\ " onclick=\ "dati( " + lblid.Text + ", ' " + (i - 1) + " ');\ "> " + zz[i] + ". " + s[i - 1] + " <br> ";



}

ll.Text = html;


//}
}

[解决办法]
RadioButtonList rbl = (RadioButtonList)e.Item.FindControl( "rblTitle ");
