How to see when a Combox.Text is empty?

Hi,

How can you see if a DataBound ComboBox is empty? When I selected an Item,
and afterwards I press "Delete" there isn't a value visible for the user,
but the applciation still 'thinks' there is a value in it: the Text-property
remains the last value, just like the SelectedIndex and SelectedValue... My
user should be able to chose either a value out of the list, or nothing (=
empty combobox).

Does anybody knows how to do this? And with which event I can trigger this,
because the MyComboBox.SelectedIndexChanged doesn't work on such a moment...

Thansk a lot in advance,

Pieter
