存儲GridView控件的多重選擇的單選按鈕的？

Question

我有gridview的其中包含60行和每行有4個單選按鈕選項（選擇的任何一個）。要運行該代碼，在提交按鈕上寫下代碼如下。我沒有工作。 我的設計圖：

<asp:GridView ID="gvSurvey" runat="server" CellPadding = "4" OnRowDataBound ="gvSurvey_RowDataBound" BorderWidth ="2" 
AutoGenerateColumns="False" EmptyDataText="No data Available" GridLines="None" 
HorizontalAlign="Center" ForeColor="#333333" Font-Names="Verdana" ShowFooter="True"> 
<RowStyle BackColor="White" /> 
<Columns> 
<asp:BoundField DataField="HEADER" HeaderText="Description" ItemStyle-HorizontalAlign="Left"

<ItemStyle HorizontalAlign="Left" /> 
</asp:BoundField> 
<asp:BoundField DataField="QTN_NO" HeaderText="Description" ItemStyle-HorizontalAlign="Left" 
FooterStyle-HorizontalAlign="Left" >

</asp:BoundField> 
<asp:BoundField DataField="SQTN_NO" HeaderText="Description" ItemStyle-HorizontalAlign="Left"

for (i = 0; i < gvSurvey.Rows.Count; i++) 
      { 
       RadioButton rdbtn1 = (RadioButton)gvSurvey.Rows[i].Cells[3].FindControl("rdbtn1"); 
       RadioButton rdbtn2 = (RadioButton)gvSurvey.Rows[i].Cells[4].FindControl("rdbtn2"); 
       RadioButton rdbtn3 = (RadioButton)gvSurvey.Rows[i].Cells[5].FindControl("rdbtn3"); 
       RadioButton rdbtn4 = (RadioButton)gvSurvey.Rows[i].Cells[6].FindControl("rdbtn4"); 


      //  RadioButton rdbtn1=(RadioButton) gvSurvey.Rows[i].ClientID 

       qtn_no = dtSurvey.Rows[i]["QTN_NO"].ToString(); 
       sqtn_no = dtSurvey.Rows[i]["SQTN_NO"].ToString(); 

       if (rdbtn1.Checked) 
       { 
        rdbtn1.Text = "1"; 
        lblMsg.Text = nominationsBiz.SaveSuggestion(ticketNo.ToString(), qtn_no, sqtn_no, rdbtn1.Text); 
       }

請通過下面的代碼，你會發現解決方案

// It will be on your submit button click 
    protected void getPinCode() 
    { 
     foreach (GridViewRow grdRows in gvSurvey.Rows) 
     { 
      RadioButton rbt1 = (RadioButton)grdRows.FindControl("rdbtn1"); 
      RadioButton rbt2 = (RadioButton)grdRows.FindControl("rdbtn2"); 
      RadioButton rbt3 = (RadioButton)grdRows.FindControl("rdbtn3"); 
      RadioButton rbt4 = (RadioButton)grdRows.FindControl("rdbtn4"); 

      string Value = RadioValue(rbt1); 
      //Similarly you can do for all radio button 
      if(!string.IsNullOrEmpty(Value)) 
      { 

       lblMsg.Text = nominationsBiz.SaveSuggestion(ticketNo.ToString(), qtn_no, sqtn_no, Value); 
      } 

     } 
    } 


    protected string RadioValue(RadioButton Rbtlst) 
    { 
     string Value = ""; 

     if (Rbtlst.Checked == true) 
     { 
      Value = Rbtlst.Text; 
     } 
     return Value; 
    }
