How to implement the standard Windows Phone 7 ComboBox replacement UI

I'm trying to implement what seems to be the standard UI replacement for comboboxes in Windows Phone 7. This is the TextBox + Navigate to New Page with Listbox approach you can see in the settings page of the Emulator.

I got the following issues while trying to implement this approach, speficically related to th开发者_运维百科e TextBox:

1. If I use a ReadOnly TextBox the text appears in light gray, which is not really what I want. I want the normal black font there.
2. If I don't use a ReadOnly TextBox the virtual phone keyboard will appear in some rare situtations, even when I handled the MouseEnter event. I can't consistently reproduce the situations when the keyboard appears.

Which is the best approach to implement this behaviour?

The Windows Phone Toolkit has a ListPicker that is quite flexible and easy to use.

Have you considered just using a TextBlock with an invisible button over the top? Or associate a gesture to take the tap event?
