一般リストがループされるまで、aspxページにいくつかのテキストボックスを入力してください

Question

aspxページの固定数のテキストボックスを入力するには、一般リストがループされ、それが埋めることができる空のテキストボックス？

私は今、以下を持っていますが、リストに答えが少ない場合は、テキストボックスがあり、outOfBoundExceptionを取得します。

else if(!IsPostBack) { 
    Groups group = new Groups(); 
    List<Answers> AnswerList = new List<Answers>(); 
    //Get the group since the session isn't null 
    group = group.getGroupbyId(int.Parse(Session["group_Id"].ToString())); 
    //Get the list of answers of the group 
    AnswerList = Answers.retrieveAnswersBygroupIdandPageNumber(group.Group_Id, pageNumberLab); 

    if (AnswerList.Count != 0) { 
     while (TextAnswerNumber < AnswerList.Count) { 
      ContentPlaceHolder cph = (ContentPlaceHolder)Master.FindControl("ContentPlaceHolder1"); 

      foreach (Control control in cph.Controls) { 
       if (control is Panel) { 
        Panel panel = (Panel)control; 
        foreach (Control controlInPanel in panel.Controls) { 

        //If the control is a textbox 
        if (controlInPanel is TextBox && controlInPanel.ID.Contains("txtAnswer")) { 
         //And if the control ID containst txtAnswer          
         //IMPORTANT: If next programmer adds another textbox for an answer textbox the ID must be in the form txtMember*". 
         TextBox answerTextBox = (TextBox)controlInPanel; 
         // Check if the textbox is empty 

         if (answerTextBox.Text == "") { 
          //If it is, fill it with the answer that group filled in when it previously answered this question. 
          answerTextBox.Text = AnswerList[TextAnswerNumber].Answer; 
          answerTextBox.ReadOnly = true; 
          TextAnswerNumber++; 
         } 
        } 
       } 
      } 
     } 
    } 
} 
      }

（場合に `（TextAnswerNumber

else if(!IsPostBack) { 
    Groups group = new Groups(); 
    List<Answers> AnswerList = new List<Answers>(); 
    //Get the group since the session isn't null

    AnswerList = Answers.retrieveAnswersBygroupIdandPageNumber(group.Group_Id, pageNumberLab); 

    if (AnswerList.Count != 0) { 
     foreach(Answer ans in AnswerList) { 
      ContentPlaceHolder cph = (ContentPlaceHolder)Master.FindControl("ContentPlaceHolder1"); 

      foreach (Control control in cph.Controls) {
