hi experts 

 anyone can tell me the way to combine headertext and headerimage like this:

              <asp:TemplateColumn HeaderStyle-CssClass="aaa" SortExpression = "SName">
            <HeaderTemplate> Name <asp:Image runat="server" ID="test"   ImageUrl="img/sortUp.gif" />
            </HeaderTemplate>
            <ItemTemplate>
                <%# DataBinder.Eval(Container.DataItem, "SName")%>
            </ItemTemplate>
            </asp:TemplateColumn>

i need you use sort icon therefore use <asp:Image runat="server" ID="test" ... to change image.

But it 's not working, with  SortExpression = "SName"

any idea  for help me?

thanks
