Hi,
I am sorry its not a tr its a span.I am using a third party menu -visual css menu.In that each table which is subscribed is embedded inside a span tag.Based on the events the span is made visible and invisible.


<ul>
<li>
<span class="qmcbox">
<table border="0" id="datagrid" cellspacing="1">
<thead>
<tr>
<th width="200">
Ask#
</th>
<th width="200">
Ask Volume
</th>
<th width="200">
Bid #
</th>
<th width="200">
Bid Volume
</th>
</tr>
</thead>
<tr id="marketOrder" source="lightstreamer" bgcolor="#ECEFF6" >
<td width="205" align="center" >
<div source="lightstreamer" field="1"></div>
</td>
<td width="200" align="center" >
<div source="lightstreamer" field="2"></div>
</td>
<td width="190" align="center" >
<div source="lightstreamer" field="3"></div>
</td>
<td width="205" align="center">
<div source="lightstreamer" field="4"></div>
</td>
</tr>
</table>
</li>
</ul>.The code works fine with chrome browser.But in IE its getting unsubscribed.
