Hi have some 'hint text' (which I set up by WatermarkContent property) in my RadAutoCompleteBox. But when I am calling RadAutoCompleteBox.Focus() in my source code, 'hint text' just despairs. How can set focus on control and save 'hint text'?
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.
