火檢查動態創建的單選按鈕的更改事件？

在下面的代碼中單選按鈕是動態創建的，但我想創建動態創建的КadioИuttons的select index change事件並處理它.....下面是不觸發事件的代碼。火檢查動態創建的單選按鈕的更改事件？

DataSet ds = SqlHelper.ExecuteDataset(sCon, "Ps_Quiz_QuestionsWithOptions_Get",sQuestions); 

if (ds.Tables.Count > 0 ?? ds.Tables[0].Rows.Count > 0)

要設置的AutoPostBack是單選按鈕。所以假，

請false改爲true

oRbOptions.AutoPostBack = true;

謝謝！當我改變oRbOptions.AutoPostBack = true;它會回傳頁面，但仍不會觸發該事件。 – 2013-03-07 14:33:45

簡單附加一個事件處理程序的檢查更改事件

oRbOptions.CheckedChanged += (s,e) => { 
    oRbOptions.AutoPostBack = true; 
}

oRbOptions.CheckedChanged + = new System.EventHandler（CheckedChanged）; oRbOptions.CheckedChanged + =（s，e）=> oRbOptions.AutoPostBack = true; };我的事件保護無效CheckedChanged（對象發件人，EventArgs e） { }仍然無法正常工作 – 2013-03-07 16:29:05
