If you want to make it private to the form you need to add the property say, oGridCustomers to the form. Then in form.Init() you may assign your grid to it:

thisform.oGridCustomers = thisform.pgfPageFrame1.Page2.grdCustomers

and then anywhere in code you may for example set and reset grid properties like:

WITH thisform.oGridCustomers
   .RecordSource = "customers"
   .Column1.ControlSource = "customers.firstname"
   .Column2.ControlSource = "customers.lastname"
   .Column3.ControlSource = "customers.address"
*** more code here***
ENDWITH

Don't forget to reset thisform.oGridCustomers to .NULL. in form.Destroy()
You can also assign your objects to the properties in application object, or create special "exchange object", so your forms can communicate through it.
