标题: 在UserControl中使用 F.ready()显示F未定义
以下这段代码定义在 UserControl中，提示F未定义。问下怎么解决这个问题。

<f

      <f:Grid ID="FilesGridID" IsFluid="true" runat="server" ShowHeader="true" ShowBorder="true" Title="附件上传" EnableCollapse="false" EnableCheckBoxSelect="false" EmptyText="" DataIDField="id">

可以看下页面生成的HTML代码，用户控件的HTML会直接生成在<form>标签内部，而F.js是在<form>标签外部引入的，所以此时还未引入F.js。

一般不要在用户控件中引入JS，因为用户控件可能会加载多次。

那Page页中通过以下形式，怎么调用到usercontrol中控件的 ClientID ?
<script type="text/javascript">
var btnDeleteFilesClientID = '<%= usercontrolID.btnDeleteFiles.ClientID %>';
</script>
