TreeView's TreeView_HoverNode error

[officecn]

Environment:
1.VS 2005,
2..NET 2.0,
3.XP SP2
4.IE 6.

I am using TreeView,and get an error,
The error is "Microsoft JScript runtime error: 'ctl00_cph_Content_LinksTreeView_Data' is undefined".

VS breaks at this point in code:
onmouseover="TreeView_HoverNode(ctl00_cph_Content_LinksTreeView_Data, this)"

I searched some issues but there are no responses.

Does ASP.NET team know about this? Has anyone seen this before? If so, any solutions?

Thanks

ctl00_cph_Content_LinksTreeView_Data作为一个变量名，它并未定义，

改为：
onmouseover="TreeView_HoverNode('ctl00_cph_Content_LinksTreeView_Data', this)"
试试~~

onmouseover="TreeView_HoverNode(ctl00_cph_Content_LinksTreeView_Data, this)" is in
^TransientScriptDocument64.Aspx,

this file is a temp file so can't modify.
and the statements like this are so many.
