Dynamically changing RoutedUICommand->Text

When is it possible to changed the Text propery of a RoutedUICommand and have
it display with the new value in a Menu? In my application it would be ideal
to set this member during the CanExecute call - at that point I know exactly
what I need to show the user ( Undo <last_cmd_here> ). The problem is that
doing so has no effect on the text displayed. I can set Text at other points
in the code and it takes affect.

There are RoutedCommand and ICommand samples in the SDK:
http://windowssdk.msdn.microsoft.com.../ms771540.aspx

The negative with the link is that it takes you to a 72 megabyte download to
Beta 2 samples. The positive is that you get a lot of samples you can easily
search through to find code samples...the RoutedCommand sample built on the
latest WPF release.

The following syntax may be of interest to you:

<CommandBinding Command="{x:Static custom:Window1.ColorCmd}"
Executed="WindowColorCmdExecuted"
CanExecute="ColorCmdCanExecute"/>

If the architecture of routed command doesn't work, you will need to
implement an ICommand which is easy to do...and there is an SDK sample too

"Give a man a fish, and you feed him for a day. Teach a man to fish, and you
feed him for a lifetime." ...I think I prefer..."Learn to fish, and feed
yourself for a lifetime."

Sorry, John. My response was for the previous post, but it still may help you
as the SDK samples in this area is very good.
