问题描述
我有一个用户控件，其根元素是网格.
I have a user control who's root element is a Grid.
我还有一个ContentControl，它用作加载数据时填充的某些文本的占位符.该控件可以在用户控件内移动，因此它的位置可以在任何地方.
I also have have a ContentControl that serves as a placeholder for some text that is filled when data is loaded. This control can be moved around within the user control and so it's position can be anywhere.
如果文本太长而无法容纳在用户控件的根Grid中，我想减小ContentControl的字体大小，直到文本适合为止.
If the text is too long to fit within the root Grid of the user control, I want to reduce the font size of the ContentControl until the text fits.
我的问题是我似乎找不到可以处理的事件.我尝试使用ContentControl.LayoutUpdated事件；但是，该事件的sender参数始终显示为空……这真的没有帮助！
My problem is that I can't seem to find an event that I can handle to do this process.I tried using the ContentControl.LayoutUpdated event;however, the sender parameter for this always appears to be nothing...which is really not helpful!
我真的很期待关于如何实现这一目标的任何建议.
I am really looking forward to any advise on how to achieve this.
谢谢

推荐答案
将ContentControl包装为仅按比例缩小的Viewbox会为您完成:
Wrapping your ContentControl in a Viewbox set to only scale down will do this for you:
<Viewbox StretchDirection="DownOnly" Stretch="Uniform">
<ContentControl Content="Some Text"/>
</Viewbox>
