How to change mode after delete in custom connector


$con = new SchedulerConnector($res);
if ($con->is_select_mode()){
//do this my custom code
else if (//Navigator status deleted){
i want to change $con mode as selected not deleted

How do i achieve this Any help really appreciated.

There is no way to change this property, it is set automatically based on request parameters.
If necessary you can delete all POST parameters and init different instance of SchedulerConnector, as there will be no POST parameters, it will init self in SELECT mode.
