PageTransition tabbing issue

If the user presses  the "< " ">" keys to move to the next or previous field, they can reach a field on a region that is not being displayed.  The display will even show portions of both regions simultaneously.

Here is what I did:
1. Add 3 iPhoneRegions to the form.  IWRegion1, IWRegion2 and IWRegion3
2. Add an edits to IWRegion1 and IWRegion2.  IWEdit1 & IWEdit2
3. Add a PageTransition to the form and sett the regions.
4. Run
5. Enter IWEdit1.
6. Press the > button when the keyboard is showing.

It will advance to IWEdit2 on IWRegion2.  Is there a way to stop this behavior?


You can set the Enabled property of the IWEdit controls on the non-visual IWRegion controls to false.
Then set it to true again when TransitionToNext or TransitionToPrevious is called.


procedure TIWForm8.TIWIPhoneHeader1AsyncRightButtonClick(Sender: TObject;
  EventParams: TStringList);
  IWEdit1.Enabled := false;
  IWEdit2.Enabled := true;

procedure TIWForm8.TIWIPhoneHeader2AsyncLeftButtonClick(Sender: TObject;
  EventParams: TStringList);
  IWEdit1.Enabled := true;
  IWEdit2.Enabled := False;

That does work with edits, but it does not work with any TTIWIPhoneButton
controls.  I have a few of those in regions.  They do not update in the PageTransition's Async events.

Unfortunately it's currently not supported to asynchronously toggle the Enabled property of a TIWIPhoneButton control.
However, this is a good suggestion and we'll consider adding this functionality in a future version.

As a workaround you can use a default TIWButton control instead.
I ended up using Gradient Buttons instead.  That gives me more control over the styling.  It would be great to see that added as a feature.  It would be nice to have that functionality on an IPhoneRegion or IPhoneScrollRegion as well.

Something that could be called, like MyiPhoneRegion.AsyncRefresh;

Thanks for the support!
