Is there a way to programmatically cancel editing a text field?

In my Windows Phone 7 application, I have a single line text box. When the user presses {ENTER}, I want to accept the value of the text field and switch the text field back to normal without editing.

Basically, is there a way to programmatically cancel editing a text field?

I tried to get Visual State Manager to normal mode, which changes the visual style, but the text field is still in edit mode and the on-screen keyboard is still displayed.

            VisualStateManager.GoToState(
                this.MyTextBox,
                "Normal",
                true);

            VisualStateManager.GoToState(
                this.MyTextBox,
                "Unfocused",
                true);

Also tried to programmatically select the parent control, but this also does not work.

I think I should skip something simple, someone must have done it a million times - any help that is greatly appreciated.

Thank,
