Custom pages with UMUI (Ultra Modern Interface)

I try to use a custom page with UMUI. The page have two radio button and one textbox and I want to make the textbox disable when one of the radio button is selected.

I try to catch the handle with ReadINIStr and WriteINIStr to use the handle to disable the textbox, and it doesn't work fine because the handle is NULL
