asp.net inline nested ternary

Hi everybody,

is it possible to nest a ternary inside an inline asp.net command?

<asp:TemplateField HeaderText="Speciality" SortExpression="DryLabTime">
                        <ItemTemplate>
                            <%#Eval("DryLabTime") == "Session1" ? "A" : 
                               (Eval("DryLabTime") == "Session2" ? "B" :
                               (Eval("DryLabTime") == "Session3" ? "C" :
                                (Eval("DryLabTime") == "Session4" ? "D" :
                                (Eval("DryLabTime") == "Session5" ? "E" :
                               "None"))))
                            %>
                        </ItemTemplate>
 </asp:TemplateField>
