网格不扩展到填充屏幕

Question

我有以下网格,它被加载到StackLayout中:

            Grid grid = new Grid {
            VerticalOptions = LayoutOptions.FillAndExpand,
            HorizontalOptions = LayoutOptions.FillAndExpand,
            RowDefinitions = 
            {
                new RowDefinition { Height = new GridLength(40, GridUnitType.Auto) },
                new RowDefinition { Height = GridLength.Auto },
                new RowDefinition { Height = GridLength.Auto },
                new RowDefinition { Height = GridLength.Auto },
                new RowDefinition { Height = GridLength.Auto },
                new RowDefinition { Height = GridLength.Auto },
                new RowDefinition { Height = GridLength.Auto },
                new RowDefinition { Height = new GridLength(40, GridUnitType.Auto) },
            },
            ColumnDefinitions = 
            {
                new ColumnDefinition { Width = new GridLength(100, GridUnitType.Auto) },
                new ColumnDefinition { Width = new GridLength(100, GridUnitType.Star) },
                new ColumnDefinition { Width = new GridLength(50, GridUnitType.Star) },
                new ColumnDefinition { Width = new GridLength(50, GridUnitType.Star) },
                new ColumnDefinition { Width = new GridLength(100, GridUnitType.Auto) },
            }
        };

        grid.Children.Add (btnMenu, 0, 1, 0, 1);
        grid.Children.Add (lblProfile, 1, 5, 0, 1);
        grid.Children.Add (btnEdit, 4, 5, 0, 1);
        grid.Children.Add (lblFirstName, 1, 2, 1, 2);
        grid.Children.Add (lblFirstNameValue, 2, 3, 1, 2);

        Content = new StackLayout { 
            HorizontalOptions = LayoutOptions.StartAndExpand,
            Children = { 
                grid
            }
        };

我已经改变了网格的宽度值和宽度类型,但我不能让它填满整个屏幕,除非我使用固定值,这在我的手机上看起来很好但在其他一切上都很糟糕.

尝试添加VerticalOptions = LayoutOptions.FillAndExpand到父级StackLayout
