Answer 1

了一個Asp.Net的ListView：

foreach(ListViewDataItem myItem in myListView.Items) 
{ 
    RadioButton btn1 = (RadioButton)myItem.FindControl("radiobutton1"); 
    RadioButton btn2 = (RadioButton)myItem.FindControl("radiobutton2"); 
    RadioButton btn3 = (RadioButton)myItem.FindControl("radiobutton3"); 

    bool AtLeastOneChecked = btn1.Checked || btn2.Checked || btn3.Checked; 

} 

新方法 - 不知道的單選按鈕＃

foreach(ListViewDataItem myItem in myListView.Items) 
{ 
    bool AtLeastOneChecked = false; 
    foreach(Control myControl in myItem.Controls) 
    { 
     try 
     { 
     RadioButton rdoTemp = (RadioButton)myControl; 
     AtLeastOneChecked = rdoTemp.Checked; 
     } 
     catch (Exception) 
     { 
      // do nothing - this probably wasn't a radio button control and errored out onthe conversion 
     } 
    }  
}
