I have an app that uses a canvas that is bigger than the screen. The app changes the size of the canvas when new items are added outside the boundaries of the canvas (usually the lower right corner). How can I move the canvas so the new items appear on screen when added? Currently I have to manually move the screen to see the new items.

推荐答案

由于需要对Canvas中子元素的绝对位置值进行编码，因此我本人避免使用Canvas，而改用Grid.

I have personally avoided using Canvas, using Grid instead, because of the need to code absolute positioning values of child elements within Canvas.

定位取决于其父级.如果其父级也是画布"，则可以使用Left或Top附加属性来移动它.

Positioning depends on its parent. If its parent is also a Canvas you can use the Left or Top attached property to move it.
