Ext.Net：radiogruop，请选择单选按钮取决于inputValue的其(Ext.Net:

我有这样一个radiogruop。

<ext:RadioGroup ID="rdyIsAktifmi" runat="server" FieldLabel="Aktifmi" Width="150" 
    Flex="1">
 <Items>
  <ext:Radio ID="Radio4" runat="server" BoxLabel="pasif" InputValue="0" />
   <ext:Radio ID="Radio5"  runat="server" BoxLabel="aktif" InputValue="1" />
  </Items>
</ext:RadioGroup>

我保存这样的cheched输入值，

rdyIsAktifmi.CheckedItems[0].InputValue //0 or one depents on cheched item

然而从代码绑定它落后时我失败了。

我tryed这一个：

 rdyIsAktifmi.CheckedItems[0].Values = employee_obj.IsAktif;(this come from database as integer value)

我也试过这一个：

rdyIsAktifmi.CheckedItems[0].Set("rdyIsAktifmi", employee_obj.IsAktif);

我怎么可以在其选择inputValue的单选depents。

**我正好找methot这样的事情。

rdyIsAktifmi.CheckedItem.InputValue = employee_obj.IsAktif;

谢谢。

我想实现这种方式。
