Add DropShadow to a Custom made Window (Blend)

问题

I am creating a custom Window form using Blend. (by setting AllowTransparency to True)

I've finished the design and it works pretty well. Now I want to add Shadow effect to it. (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.

Ok I found the answer. ( With some help from this page )

First of all, Set the window's AllowTransparency to True. Then change it's Background to No Brush

Lets say you have something like this: (Ignore the Rectangle and Borders)

Then change the Grid's Background to White color. Now click on your Window and Add about 15 pixels to its width and height.

And change the Shadow settings:

Now you can see the shadow :)

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.
