在mvc视图中将editorfor值分配给radiobutton

Question

我有一个场景，我有3个单选按钮，其中两个有默认值，而第三个我希望它应该被分配一个文本框的值。我如何在下面实现这一点是我的一些代码：

<tr>
  <td>
    <label style="padding-bottom:0.5em;font-size:1em">
      @Html.RadioButtonFor(model => model.LicenseValidityDuration, "0", new { style = "width:2em" })
      Never
    </label>
  </td>
  <td></td>
</tr>
<tr>
  <td>
    <label style="padding-bottom:0.5em;font-size:1em">
      @Html.RadioButtonFor(model => model.LicenseValidityDuration, "-1", new { style = "width:2em" })
      Always
    </label>
  </td>
  <td></td>
</tr>
<tr>
  <td>
    <label style="padding-bottom:0.5em;font-size:1em">
      @Html.RadioButtonFor(model => model.LicenseValidityDuration, model => model.LicenseValidityDuration, new { style = "width:2em" })
      Days Before Expiry
    </label>
  </td>
  <td>
    @Html.EditorFor(model => model.LicenseValidityDuration)
  </td>
</tr>
