i have a dataList that is nested.
i would like to check for various things in the nested / child data
list before displaying the data.
how do get access to the child data in a nested dataList in the
ItemDataBound event?
specifically, i would like to change the visibility of pnlMap
depending on the value of the hplMapImage URL or a fileID that i am
storing in the codebehind for the "current" file.
the code below shows the datalist in the aspx page.
<asp:DataList ID=dlEventMap
Runat=server
RepeatColumns=1
Width=100%
ItemStyle-BackColor="#FFFFFF"
CellSpacing=10
ItemStyle-CssClass="bodyheadwhite"
ItemStyle-BorderWidth=0
HeaderStyle-BorderWidth=0>
<ItemTemplate>
<tr align="left" valign="top">
<td colspan="5" class="bodyheadwhite" bgcolor="#336633">
<a name="<%# Container.DataItem("EventID") %>"></a>
<asp:Label ID=lblTitle Runat=server></asp:Label>
</td>
</tr>
<tr align="left" valign="top">
<td colspan="5" class="bodytext">
<asp:Label ID="lblEventDesc" Runat=server></asp:Label>
</td>
</tr>
<tr align="left" valign="top">
<td colspan="5" height="29">
<table width="117" border="0" cellspacing="0" cellpadding="2">
<tr>
<td width="28">
<span class="bodytext">
<asp:HyperLink ID=hplMapImage Runat=server><img

</span>
</td>
<td width="81" class="bodytext">
<asp:HyperLink ID=hplMapText Runat=server></asp:HyperLink>
</td>
</tr>
</table>
