Hi,

The following text is translated by machine, sorry, unfortunately, my English is very bad ..
if you beat one of the DocumentViewer ControlTemplate as above (copied from MSDN create). Shown in the window by using it one exception:

"Zoom" is not a valid value for the property "Command".

This error occurs only on Zoom. The program can be started normally, and the Zoom command also works. Only during the design of the error.

Thank You very much!!

The WPF team has recently reviewed this issue and will not be addressing this issue as at this time the team is focusing on the bugs impacting the highest number of WPF developers. If you believe that this was resolved in error, please reactivate this bug with any necessary supporting details.

I love the workaround #2... i.e. to solve the problem, buy another product, and thus even if you'd already spent a few thousands for VS.

Actually, I think MSDN documentation, and particularly the control template sample should be updated with the correct template or at least it should be stated that it is incorrect!!

The DocumentViewer template available on http://msdn.microsoft.com/en-us/library/aa970452.aspx is not the correct template. A tool like Blend will allow you to extract the correct control template and using that template will not exhibit the design time error described here.

This issue should be fixed by updating the documentation on MSDN.

Visual Studio appears to think there is a bug in the way NavigationCommands.Zoom has been implemented, so it won't display the window in the designer. Compiling and running works fine. However, here is how you can work around the issue:

1. Add a new file to your project that will hold a "user command" class. For this example, call it UserCommands.cs. Make it something like this:

using System;
using System.Windows.Input;

namespace UserCommands
    {
    public class ActualSizeCommand
        {
        private static RoutedCommand _actualSize;

        public static RoutedCommand ActualSize
            {
            get { return _actualSize; }
            }

        static ActualSizeCommand()
            {
            _actualSize = new RoutedUICommand("Actual size", "ActualSize", typeof(ActualSizeCommand));
            }
        }
    }

2. In your Window1.xaml file, add the following to the window definition:
    xmlns:user="clr-namespace:UserCommands"

3. Within the DocumentViewer definition in the Window1.xaml file, add a command binding:
    <DocumentViewer.CommandBindings>
        <CommandBinding Command="user:ActualSizeCommand.ActualSize" Executed="ActualSize_Executed"/>
    </DocumentViewer.CommandBindings>

4. In the code-behind file for the window, add the ActualSize_Executed handler. In the example below, 'docViewer' is the name given to the DocumentViewer instance as specified in the Window1.xaml file.

private void ActualSize_Executed(object sender, ExecutedRoutedEventArgs e)
    {
    e.Handled = true;
    NavigationCommands.Zoom.Execute(100.0, docViewer);
    }

5. In the control template for the document viewer, replace the button for NavigationCommands.Zoom with the following:

<Button Command="user:ActualSizeCommand.ActualSize"
    ToolTip="Actual Size (Ctrl+0)"
    CommandTarget="{Binding RelativeSource={RelativeSource TemplatedParent}}"
    Content="Actual Size">
</Button>

Rebuild, and you will then be able to see the window in the Visual Studio designer.
