在RadioButtonList中顯示與DataTextField不同的文本

Question

我嘗試開發基於Web的調查創建和填充ASP.NET和C＃應用程序以從Sql Server獲取數據。我使用DataBind來綁定我的問題名稱和答案。在圖片下方，我需要在RadioButtonList（不帶問題名稱）中只有問題編號（如1,2,3等）只顯示;問題名稱在標籤lblQuestion中;

protected void rbtnQuestions_SelectedIndexChanged(object sender, EventArgs e) 
    { 
     General.myquestionid = System.Convert.ToInt32(rbtnQuestions.SelectedValue); 

     lblQuestion.Text = rbtnQuestions.SelectedItem.Text; 
    } 

我還需要survey_question表的「ID」，因爲我用它在的SelectedIndexChanged事件顯示問題下面的答案。

但自從我使用DataTextField，既RadioButtonList的文本和lblQuestion.Text表現出同樣的事情。我的數據綁定方式如下：

string sqlStr = "SELECT id, question_no, question, survey_answer_type_id FROM survey_question WHERE survey_id = '" + General.mysurveyid + "'"; 
cmd = new SqlCommand(sqlStr, connection); 
da.SelectCommand = cmd; 
da.Fill(data); 

rbtnQuestions.DataSource = data; 
rbtnQuestions.DataTextField = "question"; 
rbtnQuestions.DataValueField = "id"; 
rbtnQuestions.DataBind(); 
cmd.Dispose(); 

我該如何做到這一點？ 謝謝。

在頁面加載事件設置

protected void Page_Load(object sender, EventArgs e) 
{ 
    if (!IsPostBack) 
    { 
     string sqlStr = "SELECT id,question_no, CONVERT(varchar(10),(ROW_NUMBER() over (order by question desc))) AS QueNo,question, survey_answer_type_id FROM survey_question WHERE survey_id = '" + General.mysurveyid + "'"; 
     cmd = new SqlCommand(sqlStr, connection); 
     da.SelectCommand = cmd; 
     da.Fill(data); 

     ViewState["data"] = data; 
     rbtnQuestions.DataSource = data; 
     rbtnQuestions.DataTextField = "QueNo"; 
     rbtnQuestions.DataValueField = "id"; 
     rbtnQuestions.DataBind(); 
     cmd.Dispose(); 
    } 
} 

和問題設置在SelectedIndexChanged事件

protected void rbtnQuestions_SelectedIndexChanged(object sender, EventArgs e) 
{ 
    DataSet ds = (DataSet)ViewState["data"]; 

    DataRow[] row = ds.Tables[0].Select("id = '" + rbtnQuestions.SelectedValue + "'"); 
    lblQuestion.Text = row[0]["question"].ToString();   
}
