UserControl Border background brush set in code, but I don't see that color at run-time

Question

Given the code below, I set the containing Border element on my UserControl to the given background color if a background color is given by the caller.  If I change the background Brush manually in the designer, I do see that color at run-time.  However, if I do it via the code below, I don't see any color (the Border background color is the same as the current Window).  Why doesn't setting it from code at run-time work?

   public RateMyApp(
                    string ratingMsg, 
                    string sendFeedbackEmailAddr, 
                    string rateAndReviewUrl, 
                    Color? backgroundColor = null)
        {
            this.InitializeComponent();

            if (String.IsNullOrWhiteSpace(ratingMsg))
                throw new ArgumentNullException("The rating message is empty.");

            if (String.IsNullOrWhiteSpace(sendFeedbackEmailAddr))
                throw new ArgumentNullException("The send feedback E-mail address is empty.");

            if (String.IsNullOrWhiteSpace(rateAndReviewUrl))
                throw new ArgumentNullException("The rate and review URL is empty.");

            this.RatingMessage = ratingMsg;
            this.SendFeedbackEmailAddr = sendFeedbackEmailAddr;
            this.RateAndReviewUrl = rateAndReviewUrl;
            if (backgroundColor != null)
                this.BorderBrush = new SolidColorBrush(backgroundColor.Value);

            // Show the question stack panel and hide the rate & review and send feedback stack panels.
            gridQuestion.ShowElement(true);
            gridRateAndReview.HideElement(true);
            gridSendFeedback.HideElement(true);
        }

Hi roschler,

You have a border in your user control, whats the name of the border control? I saw you set the BorderBruch for "this", and "this" means the UserControl but not the border control
