.net listview查找每行中是否选中了至少一个单选框

Question

我有一个列表视图，每行有两个或更多单选按钮控件，我想知道在提交时是否选择了至少一个单选按钮。

例如

行1      Quetison 1      radiobutton1      radiobutton2      radiobutton3

行2      Quetison 2      radiobutton1      radiobutton2      radiobutton3

在提交时我想知道用户是否在每个ROW上检查了至少一个radiobutton

Answer 1

用于Asp.Net 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 - 不知道单选按钮的数量

  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
      }
   }    
}
