To call a server side method on a client side event you need to do the following:
1- Create the server side method:
void DoSomething(...) { ... }
2- Implement the System.Web.UI.IPostBackEventHandler.RaisePostBackEvent which take one string argument (You can assign the name to the value of this argument).:
public void RaisePostBackEvent(string eventArgument)
{
DoSomething(...);
}
3- Write a script to trigger post back:
function TriggerPostBack(control, arg){
__doPostBack(control, arg);
}
4- Call the PostBack trigger function when needed:
<a .... onclick="TriggerPostBack('control', 'arg')" .. />

You can use the following way too:
<a id="myLink" href="#"
onclick="document.getElementById('<%=ServerControl.ClientID%>').Event();
return false;">OK</a>

this is such an ugly hack ;) where do you leave the button? Your other answer is much better.
