A ScrollViewer enables content to be displayed in a smaller area than its actual size. When the content of the ScrollViewer is not entirely visible, the ScrollViewer displays scrollbars that the user can use to move the content areas that is visible. The area that includes all of the content of the ScrollViewer is the extent. The visible area of the content is the viewport.
Please check ScrollViewer official document
A ScrollViewer enables content to be displayed in a smaller area than its actual size. When the content of the ScrollViewer is not entirely visible, the ScrollViewer displays scrollbars that the user can use to move the content areas that is visible. The area that includes all of the content of the ScrollViewer is the extent. The visible area of the content is the viewport.
So, if the content size large than ScrollViewer actual size, the scrollbars will display. I found you have set the grid height as 1000, if the ScrollViewer height less than 1000, the ScrollViewer will vertical scrolling. For making sure the ScrollViewer fill the page content, you need set ScrollViewer VerticalAlignment and HorizontalAlignment as Stretch.
