I am creating a portal type dashboard for our app. The controls are added on the fly. I have a page, with a tabcontrol. In the tab control I add TabItems on the fly with a canvas on it. The canvas handles the mouse events to move the controls around.
我正在为我们的应用创建门户类型仪表板。控件即时添加。我有一个页面，带有tabcontrol。在选项卡控件中，我在其上添加了TabItems，并在其上添加了一个画布。画布处理鼠标事件以移动控件。
I need to allow the users to create a layout bigger than the current size of the tab item... so I inserted a scrollviewer in the tab item and put the canvas onto it. However, the canvas doesn't seem to expand automatically to contain the content.
我需要允许用户创建一个大于选项卡项当前大小的布局...所以我在选项卡项中插入了一个scrollviewer并将画布放到它上面。但是，画布似乎不会自动展开以包含内容。
How can I made the canvas expand to hold all its content within the scroll viewer which will allow me to scroll around the canvas it contains?
如何使画布展开以在滚动查看器中保存其所有内容，这将允许我滚动它包含的画布？
