you confirm delete code has to support validation and postback itself.

btnDelete.Attributes.Add("onclick", string.Format("return
ConfirmDelete('{0}');",btnDelete.UniqueId)

function ConfirmDelete(id)
{
    if (window.confirm("really?")
    && (typeof(Page_ClientValidate) != 'function' || Page_ClientValidate())
    {
         __doPostBack(id,'');
    }
    if (document.all) event.returnValue = false; // hack for ie bug
    return false;
}
