Show Me The Template

Show Me The Template application was designedto be a useful tool for exploring the templates, be their data, control or items panel, that comes with the controls built into WPF for all 5 themes.
In addition to the learning experience this provides its also a handy way to start when youre building your own templates instead of starting from scratch.
To use Show Me The Template, run it, selecting the name of the control on the left that youd like to explore. On the right, the list of templates for that control will be shown for the currently selected theme (which you can change to see how a control is rendered in different themes).
The XAML for each of the controls templates is shown in an instance of the WebBrowse control, but you can get the XAML out by right-clicking on the template and choosing View Source. You should be able to paste the XAML into your own custom control styles as a starting place for your custom templates.
