一个脚本操作TreeView的问题,大家帮帮忙啊,弄了一天没搞定

我的文件如下:
<%@ Register TagPrefix="uc1" TagName="DossierTypeTree" Src="DossierTypeTree.ascx" %>
<%@ Page language="c#" Codebehind="DossierTypeSelect.aspx.cs" AutoEventWireup="false" Inherits="Project.Dossier_Web.DossierTypeSelect" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" >
<HTML>
<HEAD>
<title>选择档案类型</title>
<meta name="GENERATOR" Content="Microsoft Visual Studio .NET 7.1">
<meta name="CODE_LANGUAGE" Content="C#">
<meta name="vs_defaultClientScript" content="JavaScript">

<script language="javascript">
function ConfirmSelection()
{
/*var nodeIndex = tvDossierType.selectedNodeIndex;
var l_node = tvDossierType.getTreeNode(nodeIndex);
*/
var dType = document.all("tvDossierType");
l_node = dType.getTreeNode(dType.selectedNodeIndex);
window.returnValue = new Array();
window.returnValue[0] = l_node.getAttribute("ID");
window.returnValue[1] = l_node.getAttribute("Text");
window.close();
}

</script>
</HEAD>
<body MS_POSITIONING="GridLayout" leftMargin="0" topMargin="0">
<form id="Form1" method="post" runat="server">
<INPUT class="ButtonCss" type="button" value="确定" style="Z-INDEX: 101; LEFT: 88px; WIDTH: 32px; POSITION: absolute; TOP: 328px; HEIGHT: 19px"
size="1" onclick="ConfirmSelection()">
<DIV style="Z-INDEX: 102; LEFT: 0px; OVERFLOW: auto; WIDTH: 280px; POSITION: absolute; TOP: 0px; HEIGHT: 320px"
ms_positioning="FlowLayout">
<uc1:DossierTypeTree id="tvDossierType" runat="server"></uc1:DossierTypeTree>
</DIV>
</form>
</body>
</HTML>

问题:
上边引用的是一个ascx文件,是一个treeview的绑定.但在这个页面却无法用
var nodeIndex = tvDossierType.selectedNodeIndex 或
var dType = document.all("tvDossierType") 获取到,总是提示tvDossierType未定义,
大侠们帮帮啊
