By calling the GridViewBruger.DataBind() on code behind the GridView will be updated.

Also if you add the update button, inside the update panel, and on code behind also just call the DataBind() also the grid view will be updated.

.....
                </asp:GridView>                         
              <asp:Button ID="btn" Text="testUpdatePanel" runat="server" OnClick="btn_Click" />
        </ContentTemplate>
     </asp:UpdatePanel>
