如何得到Repeater的FooterTemplate中的DropDownList(ddListMove)的实例，想在page_load中为它添加项，高手帮忙解决下：
<asp:Repeater ID= "Repeater1 " OnItemDataBound= "Repeater1_ItemDataBound " runat= "server ">
<HeaderTemplate>
<table width= "98% " border= "0 " class= "huitable " cellpadding= "0 " cellspacing= "0 ">
<tr class= "top " align= "center ">
<td> 邮件主题 </td>
<td width= "28px "> </td>
<td width= "139px "> 时间 </td>
<td width= "30px "> 操作 </td>
</tr>
</HeaderTemplate>
<ItemTemplate>
