How to create a new controller?

Could anyone helps me?

I see in crm that one form can use controller of another form ( i.e. companies uses controller navigation ).
I’d wanted , looking to crm, to make the same.
So, i made a solution in which i created two forms: form1(controller default); form2.
Then i think that i have :

  1. to create a new controller;
  2. to assign it to form1;
  3. To assigng it to form2 so that form2 can be called as part of form 1.

The problem for me is that when i click on default controller, property editor windows appears me, but, from there, it is impossible for me to create a new controller .

Tanks in advance

  1. create “form1” that’s going to be your controller
  • set width property to a decent value (~200)
    -set showInMenu property disabled
    -set controller property to none

2)create form 2 and 3

  • set their controller property to “form1”
