asp.hyperlink in gridview Format 0 as null
<p>I am calling a giant stored proc via linq to sql that brings back some numbered data from 0 to 9.  I would like to be able to display any zeros as nulls (so there is no hyperlink).  I could do this in my stored procedure, but it would make it really hard to read and maintain (there is a lot of case logic going on).</p>

<p>I have the following code linking my procs results to the linqdatasource.  Is there a way to update all records by formatting the data before binding or after the fact on the hyperlink?</p>

<pre><code>protected void LinqMainMenu_Selecting(object sender, LinqDataSourceSelectEventArgs e)
{

   var db = new App_Data.MYAppDataContext();
   e.Result = db.sp_MainMenuTest( (Int16)Session["myid"]);

}
</code></pre>

<p>Thanks</p>
