Hello,
I want to have this HTML result :
<table>
<tr class="EvenContentRow" onclick="nodeClick(this)">
<td class="Expander"><img class="ExpanderOut" onmouseover="if ( 
this.className != 'ExpanderIn') this.className = 'ExpanderIn';" 
onmouseleave="this.className = 'ExpanderOut';" src="expander.gif" 
id="expander"></td>
<td><a href="#">Call Janet for tonights dinner</a></td>
<td>Finished</td>
<td>1/9/2002</td>
<td>1/9/2002</td>
<td>07:00:00</td>
</tr>
<tr style="display:none">
<td></td>
<td colspan="99">
<div class="ExpandedDetail"><span style="width:240px;padding:4px;font-
size:8pt"><span style="width:110px;color:gray;">Reminder Activated :
     </span>False</span><span style="width:240px;padding:4px;font-
size:8pt"><span style="width:110px;color:gray;">Finished On :
     </span>24/8/2002</span><span style="width:240px;padding:4px;font-
size:8pt"><span style="width:110px;color:gray;">Percent Finished :
     </span>1.000</span><span style="width:240px;padding:4px;font-
size:8pt"><span style="width:110px;color:gray;">Task Total :
     </span>0</span><span style="width:240px;padding:4px;font-
size:8pt"><span style="width:110px;color:gray;">Task Accomplished :
     </span>0</span><span style="width:240px;padding:4px;font-
size:8pt"><span style="width:110px;color:gray;">Distribution Criteria :
     </span>Normal</span><span style="width:240px;padding:4px;font-
size:8pt"><span style="width:110px;color:gray;">Priority :
     </span>Normal</span><span style="width:240px;padding:4px;font-
size:8pt"><span style="width:110px;color:gray;">Private :
     </span>False</span><span style="width:240px;padding:4px;font-
size:8pt"><span style="width:110px;color:gray;">Companies :
     </span></span></div>
</td>
</tr>
</table>

So i think that a good way will be to use a datalist inside a datagrid.
My problem is that i don't know how to do that and I haven't found any 
sample.
thanks for answers.
