How to send a value from a LinkButton to the server?

[the_Rock]

I have many LinkButton such as:\[code\]<asp:LinkButton runat="server" onclick="cmdCancellaComunicazione_Click">X</asp:LinkButton> \[/code\]they call the same server method, \[code\]cmdCancellaComunicazione_Click\[/code\]. but I need to distinguish them (passing to the server, for example, a value).How can I do it? I know there is CommandArgument, but I can't set to it a value such as <%= myValue %>
