Creating elements dynamically

Question

Hello.

I'm trying to create a button dynamically in a grid. The button appears but the features no. This is my code:

Button newButton = new Button();
            newButton.Height = 75;
            newButton.Width = 250;
            newButton.Content = "Dynamically added";
            newButton.Margin = new Thickness(302, 223, 0, 0);
            ImageBrush brush1 = new ImageBrush();
            brush1.ImageSource = new BitmapImage(new Uri("ms-appx:///Assets/Logo.png"));
            newButton.Background = brush1;
            itemGridView.Items.Add(newButton);

Thanks!
