amp; symbol rendering issue with label control

Hi,

Can any one help me.I had made a user Control say Test.ascx, i had a gridview inside two panels,i had used a Label control inside ItemTemplate Field,there when i pouplate the gridview data from my cs code,now if that label control had some data which had (& symbol e.g A&B),my page display nothing,no data,no error etc.

     I had used this user control inside a page say Test.aspx inside ajax tab container,i don't understand whether its issue with ajax tab container or something else.

here is my code of User Control

<asp:Panel ID="section7" runat="server" SkinID="1">
<asp:Panel ID="Panel2" runat="server" GroupingText="Capital" SkinID="2">
<div style="position: relative;">  
<asp:GridView ID="gv1" runat="server" AutoGenerateColumns="False" OnRowDeleting="gv1_RowDeleting"  
OnRowEditing="gv1_RowEditing">     
       <Columns>                       
                 <asp:TemplateField HeaderText="Item" HeaderStyle-HorizontalAlign="Left"> 
                      <ItemTemplate>        
              <%--<div id="c_divSubComponent" runat="Server"><%#  DataBinder.Eval(Container.DataItem,"SubComponent")%></div>--%>    <%--<asp:Label ID="c_lblSubComponent" runat="server" Text='<%#  DataBinder.Eval(Container.DataItem,"SubComponent")%>'></asp:Label>--%>      
    <asp:Literal ID="c_ltlSubComponent" runat="server"                          Text='<%# DataBinder.Eval(Container.DataItem,"SubComponent")%>' Mode="Encode">                          </asp:Literal>

 </ItemTemplate> 
<ItemStyle HorizontalAlign="Left" />
</asp:TemplateField> 
</Columns>
</asp:GridView> 
</div>        
</asp:Panel>
</asp:Panel>

 And this is the code for my Page Test.aspx

    <ajaxToolkit:TabContainer ID="TabContainer1" runat="server" SkinID="CustomStyle" ActiveTabIndex="0" >
        <ajaxToolkit:TabPanel ID="FirstTab" runat="server" HeaderText="My First Tab">
            <ContentTemplate>     
            <uc4:Test ID="uTest" runat="server" />    
         </ContentTemplate>       
  </ajaxToolkit:TabPanel>        
<ajaxToolkit:TabPanel ID="secondTab" runat="server" HeaderText="My Second Tab">   
      <ContentTemplate>             
             Tab-2  
   </ContentTemplate> 
</ajaxToolkit:TabPanel>
</ajaxToolkit:TabContainer>
