asp:hyperlink in repeater visibility

spinout · February 27th, 2008, 08:27 AM

That worked like a charm! Thanks so much for your help Imar!

By the way, I'm not sure what you mean by "Shouldn't the[list] be located in a different template like the HeaderTemplate?". Here's my entire repeater code, if you have a moment to look over it feel free to let me know what it is that I'm doing wrong.

Code:

<asp:Repeater runat="server" ID="videoRepeater">
<itemtemplate>
<div id="MainContainer">
<div id="ColumnContainer">
<div id="Column1">
<span class="TitleFont">
<p><%# DataBinder.Eval(Container.DataItem, "sVideoTitle") %></p>
</span>
<span class="StandardFont">
<p><%# DataBinder.Eval(Container.DataItem, "sVideoBlurb") %></p>
</span>
<div id="Link">[list]
<li id="video" runat="server" Visible='<%# Eval("iVideoId") IsNot DBNull.Value %>'>
<asp:Hyperlink runat="server" 
NavigateUrl='<%# "video.aspx?id=" & DataBinder.Eval(Container.DataItem, "iVideoId") %>' 
Text='Watch video'></asp:Hyperlink>
</li>
</ul>
</div>
</div>
<div id="Clear">&nbsp;</div>
</div>
<div id="Column2">
<span class="StandardFont">
<p><b>Duration:</b> <%# DataBinder.Eval(Container.DataItem, "sVideoDuration") %></p>
<p><b>Rating:</b> [<%# DataBinder.Eval(Container.DataItem, "sVideoRating") %>]</p>
<p><b>Publish Date:</b> <%# Convert.ToDateTime(DataBinder.Eval(Container.DataItem, "dVideoPublished")).ToString("d MMMM yyyy") %></p>
</span>
</div>
</div>
</itemtemplate>
<separatortemplate>
<div id="Spacer">&nbsp;</div>
</separatortemplate>
</asp:Repeater>

Maybe you're not doing anything wrong; it just depends on what you are doing. I noticed this:

Code:

[list]
<li id="video" runat="server" Visible='<%# Eval("iVideoId") IsNot DBNull.Value %>'>
  HyperLink here
</li>
</ul>

With this setup, you repeat the[list] element for each and every item in your data source. This is perfectly fine if all you want is a single bullet in front of the link, which is surrounded by other content.

However, since I didn't know your entire code, I assumed you wanted a <li> for each item in the data source and use the[list] element as a container. Normally, this is accomplished like this:

Code:

<asp:Repeater ...>
  <HeaderTemplate>[list]</HeaderTemplate>
  <FooterTemplate></ul></FooterTemplate>
  <ItemTemplate><li>...</li></ItemTemplate>
</asp:Repeater>

Here the Footer and Header define the outer[list] element. The ItemTemplate than defines individual <li> elements.

But, in your case, it seems to make sense, as you have other content in the ItemTemplate as well.

Cheers,
