calling code behind function on mouseover

Question

Hi!

i've a repeater controll with in which i'm binding dynamic links , now i've sub links within that so i just need to pass the id of the particular link to the code behind function when user moves mouse over the link....

front end code is like this ..

   <asp:Repeater ID="Repeater1" runat="server">
                            <ItemTemplate>
                                <li   >
                                <a   data-flexmenu="flexmenu4"   href="Default.aspx?id=<%# Eval("ID") %>">
                                    <%# Eval("MenuName")%>
                                </a>
</li>
                               
                            </ItemTemplate>
                        </asp:Repeater>

Now how can i pass the 'id' which i'm passing as a query string to some other page??
