For a C# Windows Phone app, how does one have a button that has a .png background, and then the background changes upon a press? To word it a little differently, how can I change the button's background image for the pressed state?
I have a button that I set the background through blend to be a png image. When I go to blend, right click the button and click edit a copy for the template, I click on the pressed state and it goes red showing it is recording. I then go to change the background image but there is a yellow border around it. I cannot change it. If I reset the value so the border goes away I get a warning saying I broke animations. If I ignore it and set it anyway, it sets the "pressed" image as the default image and all states have that image now.
I can't figure out how to make this button just be an image and then display a different image when pressed, and back to the original image when unpressed.
