Conditional display of table rows in a listview itemtemplate

I seen similar questions asked various places, but haven't really found an answer to this that works for me yet. Basically, I have a ListView where I want to hide table rows if a particular value in the data binding if a particular condition is true (most often if the value of the item is null or empty string). I've tried making the tr runat="server" and setting the condition on the visible property, but this returns a runtime error "The server tag is not well formed." Here's what I'm trying to do:

<asp:ListView runat="server" ID="FullInfoListView">
    <LayoutTemplate>
        <table class="tablestripe" width="100%">
            <asp:Placeholder runat="server" ID="itemPlaceholder" />
        </table>
    </LayoutTemplate>
    <ItemTemplate>
        <tr valign="top" class="eventrow1">
            <td colspan="2">
                <h3><%# Eval("FirstName") Eval("LastName") %></h3>
            </td>
        </tr>
        <tr valign="top" runat="server" Visible="<%# (bool)Eval("PhotoVis") %>">
            <td colspan="2">
                <img src="~/Userphoto/thumb/<%# Eval("NetworkLogin") %>.jpg" />
            </td>
        </tr>
    </ItemTemplate>
</asp:ListView>

You have to have single quotes around the Visible setter:

<tr valign="top" runat="server" Visible='<%# (bool)Eval("PhotoVis") %>'>
     <td colspan="2">
        <img src='~/Userphoto/thumb/<%# Eval("NetworkLogin") %>.jpg' />
     </td>
</tr>

You could wrap the row in a PlaceHolder:

<asp:PlaceHolder ID="PlaceHolder1" runat="server" Visible='<%# (bool)Eval("PhotoVis") %>'>
    <tr valign="top">
        <td colspan="2">   
            <img src='~/Userphoto/thumb/<%# Eval("NetworkLogin") %>.jpg' />   
        </td>   
    </tr>
</asp:PlaceHolder>

EDIT: Included single quotes around image src attribute

Try setting style="display:none" instead of using Visible.
