Hiding Elements in a Repeater

[Guest]

I'd like to hide a Hyperlink object in a repeater if the hyperlink is NULL. So,
<repeater id="rpt" runat="server">
<itemtemplate>
<%# DataBinder.Eval(Container.DataItem, "company") %> <br />
<asp:hyperlink id="lnk" navigateurl='<%# DataBinder.Eval(Container.DataItem,
"link") %>' imageurl="video.gif" runat="server" />
<itemtemplate>
</repeater>
This repeater will be bound to a Date Reader. If the link field is null,
then I'd like to make the hyperlink object invisible, to hide the image. Is
there any way to accomplish this?
Thanks,

It should be DataReader not Date Reader.

Heres a solution to my problem:
Add the following to the hyperlink tag:

visible='<%# DataBinder.Eval(Container.DataItem, "link").ToString() != "" %>'

Your solution works, but I've found odd behavior in Visual C# .NET:
when I paste your solution into my .aspx page, necessary auto-generated
code disappears the .aspx.cs file. I had to paste this back into
InitializeComponent() to get my page to work:

this.Load += new System.EventHandler(this.Page_Load);

Thats very strange. I checked and that code is in all my code-behind pages.
im not sure why yours dissappeared. Although it wont be the first
unexplained anomoly to occur in VS.Net. Hehehe.
