Gets or sets the property to use as the actual value for the items in the AdvancedComboBox
Specify the contents of the ValueMember property in cases where you bind data.
You can clear the ValueMember property by setting the property to an empty string ("") or null (Nothing in Visual Basic).
Setting a new ValueMember property raises the ValueMemberChanged and SelectedValueChanged events.
