Message:

Added dEvents.InteractiveChange?, which gets raised when a data control's value
has been changed by the user, interactively. Previously, we could only trap
ValueChanged?, which is raised when the value was changed interactively or
programatically. In addition, ValueChanged? is raised when the control's
value gets updated by the DataSource? or DataField? value changing. In short,
when you catch ValueChanged? you have no idea what the source of the change
is. With InteractiveChange?, you know it was from user input.

I've only tested this with dTextBox, but in theory it should work with all
data controls.
