Hi Teena,

Trigger bascially run's on Object event i.e. Insert, Update, Delete.  If you want to run a specific block of code on button click, follow below steps:
  1. Create apex class
  2. write method in apex class with specific block of code
  3. Link apex class with VF page as extension / controller. 
  4. Call apex method on button click. 

Thanks,

Hi Teena,

You are getting confused with the Trigger functionaity. Trigger is a piece of code that will be executed when there is any DML Operation on the record based on the Trigger event you chose.

Say for eg: When you click a button VF page, if that button does any DML operation on the SObject record then the trigger on that SObject will get executed. Means, if your Custom Button on VF page updates, inserts or deletes an Account record then if there is a trigger on the Account object defined for any of the above DML operation, then that trigger will get executed. You dont have to explicitly call trigger anywhere.

Please let me know if you need more assistance.
