Question

I was wondering how can I know which commands are implemented by the Controls delivered with the Framework. For example, how can I know if an Image implements the ApplicationCommands.Copy command or not? Or if a TextBox implements ApplicationCommands.Copy, ApplicationCommands.Cut, ApplicationCommands.Paste?

Extracted from the MSDN:

Some controls have built in CommandBindings for some commands. This
mechanism allows the semantics of a command to stay the same, while
the actual implementation is can change. A TextBox, for example,
handles the Paste command differently than a control designed to
support images, but the basic idea of what it means to paste something
stays the same. The command logic cannot be supplied by the command,
but rather must be supplied by the control or the application. Thanks
in advance.

Answer 1

So looks like the only way to know if a UserControl implements a standard command is to open it with a decompiler and look inside to see if it registers the command or not.

This is a big fail of Microsoft. This should be documented on the MSDN asap.
