您的 ScrollViewer 位于 StackPanel 内部,它会根据其内容调整大小(垂直或水平取决于其方向)。将其直接放置在窗口、网格单元格或 DockPanel 中以显示滚动条。
Your ScrollViewer is inside StackPanel which resizes to its content (either vertically or horizontally depending on its orientation). Place it either directly in a Window, a cell of a Grid, or a DockPanel for scroll bars to show up.
