An Example
To give you a taste for how control templates work, here’s a moderately complex example of a template that creates a round button with a shiny highlight. If you look at the XAML, you’ll see that the most complex part of the definition is the three gradient brushes. The rest is just a Border that contains a Grid with two ellipses. I don’t know about you, but I think that’s a pretty cool result for very little effort.
1 Create a new project to contain the sample Button and rectangular version. You’ll want to move the brush definitions from the Resources section of the control template to Window.Resources so that you can reference them from both button templates.
2 Try changing the BorderBrush color of one of the buttons (the button itself, not the button’s control template). What happens?
