>>I have never tried this, but assume that you can define your own header class programmatically, adding new property 'ID' into definition. Then, in run-time, you should remove standard header (RemoveObject) from grid.column, and add (AddObject) new header from new class.

Michel- a custom property can be added to a custom header class with syntax similar to the following
DEFINE CLASS MyHeader AS Header
mycustomproperty
mycustomproperty2 = "Initial value" && Gives property a default value
ENDDEFINE
