RadioButtonList DataBinding當以前檢查

Question

不知道爲什麼這是如此困難，但我有是沒有單選按鈕鏈接到一個字段。當記錄被調用時，我想要在單選按鈕中選擇記錄的答案（是或否）。我的代碼無法識別單選按鈕的ID。任何幫助將不勝感激。以下是代碼。

<%@ Page Title="" Language="C#" MasterPageFile="~/MasterPage.master" %> 

<script runat="server"> 

protected void frmProfiles_PageIndexChanging(object sender, FormViewPageEventArgs e) 
{ 
RadioButton selectedRadioButton = (RadioButton)sender; 
} 

protected void onYesNochanged(object sender, EventArgs e) 
{ 
if (rblYesNo.SelectedItem.Text == "yes") 
; 
else 
; 
} 
</script>

rblYesNo是一個FormView內，所以你必須做這樣的事情（未測試）：

RadioButton rb = (RadioButton)frmProfiles.Items.FindControl("rblYesNo"); 
if (rb.SelectedItem.Text == "Yes") etc
