LinkButton ClickEventHandler and firing a method

Hello there,
I am dealing with a situation where I have a linkbutton which fires a ClickEventHandler.
<asp:LinkButton ID="LinkButton1" runat="server" CommandArgument="LinkButton1" OnCommand="lb_Command">LinkButton1</asp:LinkButton>

public delegate void ClickEventHandler(object sender, CommandEventArgs e);     public event ClickEventHandler TestCustomEvent;     protected void lb_Command(object sender, CommandEventArgs e)
