Don't confuse MVP with MVC. The presenter is often the ideal target for
databinding.

Remember that the presentation system may not necessarily be the UI. For
example, take the idea of a bank account with a positive or negative
balance. The number representing the balance may be a floating point value
that has no notion of colour yet, when viewed in the UI, the number will be
black or red depending on the sign. The presenter might provide a colour
property that changes with the sign of the balance and which is databound to
the ForeColor of the textbox used to display the number.

I personally believe that data-binding is the single most important
technology in the developer's toolbox today. Just consider the change to WPF
for example. Almost every aspect of application development has changed from
the Windows Forms model _except_ databinding which has been made more
robust, performant and powerful.

The short answer is "Yes, by all means use databinding between the presenter
and the view. Its the best method!"
