这样的值传递怎么实现????

[jacklin_036]

MainForm.aspx为主框架.
left.aspx为左框架.
right.aspx为右框架
我现在要把MainForm.aspx?user=001的user值传到left.aspx和right.aspx该怎么实现,
if(!Page.IsPostBack)
{
Response.Write("window.frames[\"frmLeft\"].location='FrameFiles/Menu.aspx?UserID=" + UserID + "&UserType=" + UserType + "';");
Response.Write("document.all.OfficeMain.src='FrameFiles/OfficeMain.aspx?UserID=" + UserID + "&UserType=" + UserType + "';");
}
这样好像不能实现,有其它的方法吗??????

<frameset rows="800,*" cols="*" border="0" frameSpacing="0" frameBorder="0">
<frameset style="CURSOR: w-resize" border="0" frameSpacing="12" frameBorder="yes" cols="143,74%">
<frame name="leftFrame" borderColor="#99ccff" src="left.aspx">
<frame name="mainFrame" src="detail.aspx?ID=<%=Request.QueryString["actid"]%>
<%=Session["strmta"]=Request.QueryString["actid"]%>">
</frameset>
</frameset>
