This won't hide the repeater completely, but you can subclass the Repeater control so that it includes a GridView-like empty data template:

using System;
using System.Web.UI;
using System.Web.UI.WebControls;

public class EmptyCapableRepeater : Repeater
{
    public ITemplate EmptyDataTemplate { get; set; }

    protected override void OnDataBinding ( EventArgs e )
    {
        base.OnDataBinding( e );

        if ( this.Items.Count == 0 )
        {
            EmptyDataTemplate.InstantiateIn( this );
        }
    }
}

You can them use it in your .aspx like this:

    
        <%# Eval( "Result" )%>
    
    
        

    
    
        No results were found.
