What exactly are you still able to edit? Everything? If that's the case, then something is wrong.
Maybe your code is not getting called? Maybe you are loading a layout that is setting this property again? Or maybe the same property is getting set somewhere else in your code?
HOWTO:How can I make a grid or a column, row, or cell in the UltraWinGrid disabled or read-only?
