Ajax Accordion - Override Header events

Guys,

I am using the Accordion control from the Ajax control toolkit. The default event for the header is an expand/collapse.

In my header, I want to add a checkbox and be able to get to the checked event. At the moment, when I check it, the expand/collapse event triggers. I want to keep that action on the label in the header, but need to do something else with the checkbox. Possible?

EDIT - Hmmmmm, something about registering client side handlers I think, but thats way over my head. Any pointers please?

Thanks
Bob

                      <HeaderTemplate>
                            <asp:Label ID="SectionNameLabel" runat="server" Font-Bold="true" Font-Size="Larger"

                          <asp:CheckBox ID="sectionna" runat="server" Text="Not Applicable" />
