DataBinder.Eval problem

[B.J.]

Hi,

I have custom databound template control

<N:My id="ID" runat="server">

<Category Type="Staple">
<%# DataBinder.Eval(Container.DataItem,"Staple") %>
</Category>

<Category Type="Sub">
<%# DataBinder.Eval(Container.DataItem,"Sub") %>
</Category>

</N:My>

and in this control I need to find out whether OnItemCreated event is called
for
DataBinder.Eval(Container.DataItem,"Staple") or for
DataBinder.Eval(Container.DataItem,"Sub").
How can I find it out ?

Much thanks.
