Thanks for taking a look at this. Unfortunately, even after I make the TextView a class member, I still don't see the text displayed in the window. A concise description of the problem is this: If I make the TextView a child of the window, the text is displayed. If I make the TextView a child of a Grid, and the Grid a child of the window, the text is not displayed.
I am assuming there might be some property of the Grid I need to set?
