Hello Roman,
In order to achieve the desired you need to set the
WatermarkBehavior property of the
WatermarkTextBox placed inside the
AutoCompleteBox to
HideOnTextEntered. For that purpose you could use the
ChildrenOfType method to get the
WatermarkTextBox and set its property.
Please, check the attached sample that demonstrates that approach.
Hope this helps.
Regards,
