我有一个带有堆栈面板和框架的窗口。保存我的菜单的堆栈面板。在选择菜单时，我正在框架内加载我的用户控件。

但问题是 UserControl 显示在框架的中心并且没有最大化。

谁能帮我将我的 UserControl 最大化到 Frame 的宽度并调整 UserControl 中所有控件的大小？

这是我的 xaml 文件...

当您将 frame1 的内容设置为 UserControl 的实例时，它将采用框架的大小。您觉得它没有被最大化的原因是因为您在 UserControl 中设置了元素的高度和宽度（如 ScrollViewer 宽度）。只需将 UserControl 的背景设置为某种颜色，在运行时您会看到它占用了框架的大小。但是用户控件中的内容并没有占用用户控件的大小。

WPF 布局与 Winforms 不同，专门设置所有控件的高度和宽度不是一个好习惯。控件根据其内容呈现自己。
