Add DropShadow to a Custom made Window (Blend)
提问by xperator
I am creating a custom Window form using Blend. (by setting AllowTransparencyto True)
我正在使用Blend创建一个自定义 Window 表单。（通过设置AllowTransparency为True）
I've finished the design and it works pretty well. Now I want to add Shadow effect to it. (DropShadowEffect)
我已经完成了设计，效果很好。现在我想给它添加阴影效果。( DropShadowEffect)
I can't do that because the Window itself is hidden so the effect won't show. And it doesn't work on the main Grid. No luck with adding a border and give the shadow to it.
我不能这样做，因为 Window 本身是隐藏的，所以效果不会显示。它不适用于主网格。添加边框并为其添加阴影没有运气。

Ok I found the answer. ( With some help from this page)
好的，我找到了答案。（在此页面的一些帮助下）
First of all, Set the window's AllowTransparencyto True. Then change it's Backgroundto No Brush
首先，将窗口设置AllowTransparency为True。然后改变它的Background到No Brush
Lets say you have something like this: (Ignore the Rectangle and Borders)
假设您有这样的事情：（忽略矩形和边框）
Then change the Grid's Backgroundto White color. Now click on your Window and Add about 15 pixels to its width and height.
然后将网格更改Background为白色。现在单击您的窗口并为其宽度和高度添加大约 15 个像素。
And change the Shadow settings:
并更改阴影设置：
Now you can see the shadow :)
现在你可以看到阴影了:)
I think you got the idea how this is working. Remember you can still play around with the Window height/weight and the Shadow settings to get a better effect.
我想你知道这是如何工作的。请记住，您仍然可以使用窗口高度/重量和阴影设置来获得更好的效果。
