namespace SDKSample
    public partial class CharacterCasingExample : Page

            StackPanel myStackPanel = new StackPanel();

            //Create TextBox
            TextBox myTextBox = new TextBox();
            myTextBox.Width = 100;

            // The CharacterCasing property of this TextBox is set to  
            // "Upper" which causes all manually typed characters to 
            // be converted to upper case.
