How to hide this?

[Shapper]

Hello,

I have this in a Repeater on na Asp.Net page:
<a href='<%# DataBinder.Eval(Container.DataItem, "link") %>'>Go</a>

How to hide everything is the link field is empty?

Thanks,
Miguel

I'd just add check for the link being empty, and if it's true then set the
style "display:none" within the "<a>" tag. It would look like this:
<%
//Define a function to check the value and return the "none" or ""
attribute for "display"
string HideLink ( val )
{
return (val== null || val=="")?"none":"");
}
%>

<a href='<%# DataBinder.Eval(Container.DataItem, "link") %>'
style='display:<%=HideLink(# DataBinder.Eval(Container.DataItem, "link") )%>

Go</a>
I haven't tested it, so I'm not sure about the syntax, but just try it.

Choices:

1. Filter the data to ensure only those with valid links are bound.
2. Move away from declarative binding and create the links programatically
and then bind them to a container (panel comes to mind).
3. If this is a single row, you can make the repeater invisibible when the
value is empty.

These are the first ideas that come to mind. Of the ideas, #1 is my favorite
as it filters out junk and does not process it at all.
