Databound combo text property always blank after binding.

[Greg]

I have a databound combo box that after binding the data to it, if when
the text property is queried, always returns a blank string, until the
user interacts with it and changes the index (from 0 to somethign
else). However, immediately after the data is bound, if set the index
to -1 and then back to 0, the text prooperty is non-blank. Can anyone
explain what is going on here? I would rather a more sophisticated
approach than toggling the index in order to get the initial value out
of it!

Regards,

Greg.
