Javascript Onclick To Select Item With Asp.net Listview Control

I'm trying to implement a onclick event to select an item in a asp:ListViewControl.

publicclassListViewEvent : ListView, IPostBackEventHandler
    {
        publicvoidRaisePostBackEvent(string eventArgument)
        {
            if (!eventArgument.Contains("$"))
                return;

            string[] splitEventArgument = eventArgument.Split('$');

            switch (splitEventArgument[0])
            {
                case"Select":
                    {
                        SelectItem(Convert.ToInt32(splitEventArgument[1]));
                        break;
                    }
                default:
                    {
                        break;

                    }
            }
        }
    }
