I don't think there is a way in ASP.NET, but you can always do it in CSS just use HeaderStyle-CssClass on your template.

UPDATE:

Ok, I was wrong, ASP.NET does support this functionality, you just need use a HeaderTemplate in your TemplateField.

<asp:TemplateField SortExpression="Subnet" HeaderText="Subnet">
   <HeaderTemplate>
       <asp:Label ID="SubnetHeader" ToolTip="My Tip to you" runat="server" Text="Label"></asp:Label>
   </HeaderTemplate>

   <ItemTemplate >  
       <asp:Label ID="lblSubnet" runat="server" Text='<%# Bind("Subnet") %>' ></asp:Label>       
   </ItemTemplate>
</asp:TemplateField>

tnks @Limey .. how to add a title with CSS ??

Lawrence Over a year ago

Thanks Limey. However, I found this broke the SortExpression. If I use asp:LinkButton instead of asp:Label I can add a command to sort the column. See here for more details link
