I am using visualTreeHelper to get list of all the elements present on screen ,irrespective of which user control they are present in .

        Panel theParent = VisualTreeHelper.GetParent(this) as Panel;
        theParent.FindName("Name of the element")

Hope you are using MVVM pattern .If yes , add a view model property for the text and bind this to the textbox .

Update this property whenever you want to change the value of the text box.

Use a visibility converter if you want to change the visibility also.
