I have created a local variable that will fetch all the tasks from a process report. When there is a change in the task,i.e. i have accepted or assigned or completed the task, or added a new task, it should automatically refresh the grid and show the change in it. How to do this process?

Push vs Pull.
Whenever there is change in the task it cannot push the change to the dependents, it has to be pull from the dependents (An interface in your case). Only option you left with is to refresh local variable at some time interval.
