doesnt bind from database when there isnt any data

Hi

In Product.aspx page I have repeater that bind it from Subset_Menu table from database

<li class="current">
                                    <asp:LinkButton id="awood" class="AWoodI" runat="server" onclick="Mobile_Click">&nbsp</asp:LinkButton>
                                    
                                    <ul>
                                         <asp:UpdatePanel ID="UpdatePanel1" runat="server">
                                        <ContentTemplate>
                                        <asp:Repeater ID="RptMobile" runat="server"   >
                                            <ItemTemplate>
                                                <li>
                                                <a href='<%#"Product.aspx?subset="+Eval("subset")+"&ID="+Eval("ID")+"&ListType="+(DataList1.Visible == true ? "Product" : "Store")%>'>
                                             
                                                    <%#Eval("subset")%></a> </li>
                                            </ItemTemplate>
                                        </asp:Repeater>

and SP

select  subset,id
 from subset_menu
where H_name='computer'
order by  SubsetId desc
end

and below is Subset_menu table

now according to Sp I want in repeater shows SoftWare and Hardware where H_name is Computer

but Here it shows  Software,"Space" and Hardware I mean it shows NULL value in repeater becuse in row with id=2 isn't any data so it shows space instead of data in repeater

I want if in Subset column wasn't any data It doesn't bind any thing from this row...

How I can do it?

Best Regards
