Filter automatically on Form

Hi , There may be some requirement that we need to have Filter by grid on form available.
One way of achieving this is , Go to Tools -> Options and Mark Filed by grid on default .
The disadvantage of this , all form will have this functionality and System will slow down.
Then , how to enforce this on only selected forms :
Here you go , place the below line of code in Run method of form after Super();

 this.task(2855);

;
 you will have Filter on only that particular form.

Thanks
