I'm looking for something like a pdf or anything else that would show a chart of available controls in SL and/or WPF.
Ideally, the chart should have a drawing of the control, some succinct description and the hierarchy if possible.
Has anyone seen such a thing? Freeware or Payware, can even be from a book I could buy.
The controls that are shipped with the platform are fairly straightforward, so I'm not sure that would even make sense - i.e. the basic buttons, input box, text block, etc.
As for the controls that are shipped with the Toolkit, which is the richer feature set released out of band in relation to the Silverlight trunk, you can preview everything you asked for here:

What's more, the source code for the preview is included with the tool kit so it's very easy to see how any of those controls were used.
