No, this is not what you think this is. This is a proof of a concept .Net CF v2 program that I've put together during my 2 train rides home and to work. And yes, the button does slide. The code is pretty simple. It just draws the images in the right places with transparency. The transparency is achieved by using AlphaBlend API function that's become available in Windows CE 5.0. I think this proves that the UI's that we can create in CF are not limited to the usage of a standard controls. With enough creativity we can spice up our applications with this kind of eye candy.
