Question

有没有人知道我是否可以缩小现有的DataTemplate？换句话说，如果我有一个显示一组文本块的DataTemplate，以及大小为300乘300的图像，我可以将该DataTemplate缩小到50x50以创建视图而不修改DataTemplate本身吗？

我有几个DataTemplates用于图中显示的不同元素。我想对这些DataTemplate进行缩小（预览），以便将其作为列表或一组显示给用户。

目前我唯一的选择是手动将其缩小到预览尺寸，但我想知道是否有一个可以用来自动缩小它的功能。

提前致谢。

最简单的方法是将模板的容器包装在Viewbox中。 Viewbox会扩展其内容以适应自己。

由于DataTemplate通常用于ItemsControl，因此您可能需要使用自定义容器来利用模板周围的视图。

如何在wpf中压缩或缩小现有的DataTemplate？
