如何在 UWP 中放大滚动查看器，但保持滚动查看器的宽度和高度拉伸以适合父面板或网格列？

Question

See the images below. One is at 78% zoom but the whole content is zoomed out but not stretching to its parent control despite having Horizontal and Vertical Alignment set to "stretch".

ScrollViewer is in a GridColumn and GridRow and the Grid is being loaded into a Frame which is a part of the NavigationView on the mainpage.

Desired effect is for the content to get smaller but fit to the width and height to show more columns in this case.

This behavior of ScrollViewer is by-deign, derive from the screenshot the DataGrid is a whole place. When we zoom in or out, The DataGrid will zoom overall. For the requirement, you could edit the DataGrid's MaxColumnWidth property when zoom.
