Hey, venkat it's possible.. you need to call bactapex execution from the buttons action method and it will work.

Thank you

dude you need to call only Start method .. Others will call automatically.

It shows error  ...Method does not exist or incorrect signature: Batchexamupdate.start() ,Batchexamupdate is my batchapexcalss name...
Niket SFNiket SF
Batchexamupdate objBatchexamupdate = new Batchexamupdate();
ID batchprocessid = Database.executeBatch(objBatchexamupdate);


you need to start in this way .. it will call start method --> then execute -> then --> finish..


Thank you

Batchexamupdate objBatchexamupdate = new Batchexamupdate(); ID batchprocessid = Database.executeBatch(objBatchexamupdate);

I Use  ths code  n Controller class as batchcall,it shows the error as constructor not defined for Batchexamupdate...

Then write the constructor :)

public Batchexamupdate()
{
}

Done.

Thank you
