Just manually set the button status.  There are a lot of factors as to how to control the state of buttons...but you can always overwrite any native behavior by simply setting the button status:

I have a wizard that has only a single page at design time, then I add a bunch at runtime (all of which is working great). The only hick-up is that the when the wizard is initially shown, there are only three buttons for the wizard: back (disabled), finish (enabled) and Cancel (enabled). I'm using a tree view as a second navigation control and when I move to any other page then back to the first page, the buttons are then correct (back, next and cancel all disabled/enabled correctly). So the question is how do I update the wizard so it updates the controls after adding pages in code? I tried Refresh and Update but neither worked.
