推荐答案

你遇到的问题是，Canvas与许多WPF面板和容器不同，它不会与内容相匹配，这意味着如果添加一个超出canvas边界的元素，因此，在ScrollViewer中嵌入一个Canvas不会有好处，除非你手动更新Canvas的大小。

The problem you're running into is that Canvas, unlike many WPF panels and containers, does not size to contents. That means if you add an element which goes outside the canvas boundaries it will not update it's size. Hence embedding a Canvas in a ScrollViewer will do no good unless you manually update the size of the Canvas.

这听起来像你想要的是一个Canvas

It sounds like what you want is a Canvas which supports size to contents. This blog entry has exactly that control.
