Most certainly NOT impossible. All you have to do to suppress the prompt is omit the "return" statement. Returning any value will cause the prompt to fire. Example:

           window.onbeforeunload = function saveAllData()
            {
                //Invoke AJAX method to save DataTable in database
                [classname].SaveDataTable();
                //return true;                      //comment out 'return' to suppress prompt
            }

            function SaveDataTable_Callback(response) 
            {
                //alert(response);
            }
